MPLS Traffic Engineering Commands
This module describes the commands used to configure Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) on .
Your network must support the following Cisco features before you can enable MPLS-TE:
- MPLS
- IP Cisco Express Forwarding (CEF)
- Intermediate System-to-Intermediate System (IS-IS) or Open Shortest Path First (OSPF) routing protocol
- Resource Reservation Protocol (RSVP)
MPLS Label Distribution Protocol (LDP), Resource Reservation Protocol (RSVP), and Universal Control Plane (UCP) command descriptions are documented separately.

adjustment-threshold (MPLS-TE)
To configure the tunnel bandwidth change threshold to trigger an adjustment, use the adjustment-threshold command in MPLS-TE automatic bandwidth interface configuration mode. To disable this feature, use the no form of this command.
adjustment-threshold percentage [ min minimum bandwidth ]
no adjustment-threshold percentage [ min minimum bandwidth ]
Syntax Description
percentage
Bandwidth change percent threshold to trigger an adjustment if the largest sample percentage is higher or lower than the current tunnel bandwidth. The range is from 1 to 100. The default is 5.
min minimum bandwidth
(Optional) Configures the bandwidth change value to trigger an adjustment. The tunnel bandwidth is changed only if the largest sample is higher or lower than the current tunnel bandwidth, in kbps. The range is from 10 to 4294967295. The default is 10.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
If you configure or modify the adjustment threshold while the automatic bandwidth is already running, the next band-aids application is impacted for that tunnel. The new adjustment threshold determines if an actual bandwidth takes place.
Examples
The following example configures the tunnel bandwidth change threshold to trigger an adjustment:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# auto-bw RP/0/RP0/CPU0:router(config-if-tunte-autobw)# adjustment-threshold 20 min 500Related Commands
Command

Configures automatic bandwidth on a tunnel interface and enters MPLS-TE automatic bandwidth interface configuration mode.
Configures the minimum and maximum automatic bandwidth to set on a tunnel.
Enables only the bandwidth collection without adjusting the automatic bandwidth.
Configures tunnel overflow detection.
Displays information about MPLS-TE tunnels.
admin-weight
To override the Interior Gateway Protocol (IGP) administrative weight (cost) of the link, use the admin-weight command in MPLS-TE interface configuration mode. To return to the default behavior, use the no form of this command.
Syntax Description
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
To use MPLS the admin-weight command for MPLS LSP path computations, path-selection metric must be configured to TE.
Task ID
Examples
The following example shows how to override the IGP cost of the link and set the cost to 20:RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# interface POS 0/7/0/0 RP/0/RP0/CPU0:router(config-mpls-te-if)# admin-weight 20affinity
To configure an affinity (the properties the tunnel requires in its links) for an MPLS-TE tunnel, use the affinity command in interface configuration mode. To disable this behavior, use the no form of this command.
affinity { affinity-value mask mask-value | exclude name | exclude-all | include name | include-strict name }
no affinity { affinity-value mask mask-value | exclude name | exclude-all | include name | include-strict name }
Syntax Description
affinity-value
Attribute values that are required for links to carry this tunnel. A 32-bit decimal number. Range is from 0x0 to 0xFFFFFFFF, representing 32 attributes (bits), where the value of an attribute is 0 or 1.
mask mask-value
Checks the link attribute. A 32-bit decimal number. Range is 0x0 to 0xFFFFFFFF, representing 32 attributes (bits), where the value of an attribute mask is 0 or 1.
exclude name
Configures a particular affinity to exclude.
exclude-all
Excludes all affinities.
include name
Configures the affinity to include in the loose sense.
include-strict name
Configures the affinity to include in the strict sense.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Affinity determines the link attributes of the tunnel (that is, the attributes for which the tunnel has an affinity). The attribute mask determines which link attribute the router should check. If a bit in the mask is 0, the attribute value of a link or that bit is irrelevant. If a bit in the mask is 1, the attribute value of that link and the required affinity of the tunnel for that bit must match.
A tunnel can use a link if the tunnel affinity equals the link attributes and the tunnel affinity mask.
Any properties set to 1 in the affinity should be 1 in the mask. The affinity and mask should be set as follows:
tunnel_affinity=tunnel_affinity and tunnel_affinity_maskYou can configure up to 16 affinity constraints under a given tunnel. These constraints are used to configure affinity constraints for the tunnel:
- Include constraint
Specifies that a link is considered for CSPF if it contains all affinities associated with the include constraint. An acceptable link contains more affinity attributes than those associated with the include statement. You can have multiple include statements under a tunnel configuration.
- Include-strict constraint
Specifies that a link is considered for CSPF if it contains only the colors associated with the include-strict statement. The link cannot have any additional colors. In addition, a link without a color is rejected.
- Exclude constraint
Specifies that a link satisfies an exclude constraint if it does not have all the colors associated with the constraint. In addition, a link that does not have any attribute satisfies an exclude constraint.
- Exclude-all constraint
Specifies that only the links without any attribute are considered for CSPF. An exclude-all constraint is not associated with any color; whereas, all other constraint types are associated with up to 10 colors.
You set one bit for each color; however, the sample output shows multiple bits at the same time. For example, you can configure red and black colors on GigabitEthernet0/4/1/3 from the interface command. The sample output from the show mpls traffic-eng link-management interfaces command shows that the Attributes field is set to 0x21, which means that there are 0x20 and 0x1 bits on the link.
Task ID
Examples
This example shows how to configure the tunnel affinity and mask:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# affinity 0101 mask 303This example shows that a link is eligible for CSPF if the color is red.. The link can have any additional colors.
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# affinity include redThis example shows that a link is eligible for CSPF if it has at least red and black colors. The link can have any additional colors.
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# affinity include red blackThis sample output shows that the include constraint from the show mpls traffic-eng tunnels command is 0x20 and 0x1:
Name: tunnel-te1 Destination: 0.0.0.0 Status: Admin: up Oper: down Path: not valid Signalling: Down G-PID: 0x0800 (internally specified) Config Parameters: Bandwidth: 0 kbps (CT0) Priority: 7 7 Number of configured name based affinity constraints: 1 Name based affinity constraints in use: Include bit map : 0x21 Metric Type: TE (default) AutoRoute: disabled LockDown: disabled Loadshare: 0 equal loadshares Auto-bw: disabled(0/0) 0 Bandwidth Requested: 0 Direction: unidirectional Endpoint switching capability: unknown, encoding type: unassigned Transit switching capability: unknown, encoding type: unassigned Reason for the tunnel being down: No destination is configured History:This example shows that a tunnel can go over a link that contains red or black affinity. A link is eligible for CSPF if it has a red color or a black color. Thus, a link with red and any other colors and a link with black and other additional colors must meet the constraint.
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# affinity include red RP/0/RP0/CPU0:router(config-if)# affinity include blackThis sample output shows that the include constraint from the show mpls traffic-eng tunnels command is 0x20 or 0x1:
Name: tunnel-te1 Destination: 0.0.0.0 Status: Admin: up Oper: down Path: not valid Signalling: Down G-PID: 0x0800 (internally specified) Config Parameters: Bandwidth: 0 kbps (CT0) Priority: 7 7 Number of configured name based affinity constraints: 2 Name based affinity constraints in use: Include bit map : 0x1 Include bit map : 0x20 Metric Type: TE (default) AutoRoute: disabled LockDown: disabled Loadshare: 0 equal loadshares Auto-bw: disabled(0/0) 0 Bandwidth Requested: 0 Direction: unidirectional Endpoint switching capability: unknown, encoding type: unassigned Transit switching capability: unknown, encoding type: unassigned Reason for the tunnel being down: No destination is configured History:This example shows that a link is eligible for CSPF if it has only red color. The link must not have any additional colors.
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# affinity include-strict redThis example shows that a link is eligible for CSPF if it does not have the red attribute:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# affinity exclude redThis example shows that a link is eligible for CSPF if it does not have red and blue attributes. Thus, a link that has only a red attribute or only a blue attribute is eligible for CSPF.
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# affinity exclude red blueThis example shows that a link is eligible for CSPF if it does not have either a red or a blue attribute:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# affinity exclude red RP/0/RP0/CPU0:router(config-if)# affinity exclude blueaffinity-map
To assign a numerical value to each affinity name, use the affinity-map command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.
affinity-map affinity name { affinity value | bit-position value }
no affinity-map affinity name { affinity value | bit-position value }
Syntax Description
affinity name
Affinity map name-to-value designator (in hexadecimal, 0-ffffffff ).
affinity value
Affinity map value designator. Range is from 1 to 80000000.
bit-position
Configures the value of an affinity map for the bit position of the 32-bit number.

attribute-flags
To configure attribute flags for an interface, use the attribute-flags command in MPLS-TE interface configuration mode. To return to the default behavior, use the no form of this command.
Syntax Description
attribute -flags
Links attributes that are compared to the affinity bits of a tunnel during selection of a path. Range is 0x0 to 0xFFFFFFFF, representing 32 attributes (bits) where the value of an attribute is 0 or 1.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
The attribute-flags command assigns attributes to a link so that tunnels with matching attributes (represented by their affinity bits) prefer this link instead of others that do not match.
The interface attribute is flooded globally so that it can be used as a tunnel headend path selection criterion.
Task ID
Examples
The following example shows how to set attribute flags to 0x0101:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# interface POS 0/7/0/0 RP/0/RP0/CPU0:router(config-mpls-te-if)# attribute-flags 0x0101Related Commands

Command History
Release Modification Release 4.2.0
This command was introduced. The sub-pool keyword is not supported.
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
The values specified for an attribute within a path-option attribute-set does not prevent the configuration of the same attribute at the tunnel level. However, only one level is taken into consideration. The configuration at the path-option level is considered more specific than the one at the level of the tunnel, and is therefore used.
Attributes that are not specified within an attribute-set picks their default values, as usual, from the configuration at the tunnel level, the configuration at the global mpls level, or default values.
An XRO attribute-set can be specified as part of the path-option, if required. An empty XRO attribute set results in the GMPLS tunnel being signaled with no exclusions, and therefore no XRO.
Task ID
Examples
This example shows how to configure an attribute-set to a TE interface for an auto-mesh tunnel:
RP/0/RP0/CPU0:router# config RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# auto-tunnel mesh RP/0/RP0/CPU0:router(config-te-auto-mesh)# group 1 RP/0/RP0/CPU0:router(config-te-mesh-group)# attribute-set am1 RP/0/RP0/CPU0:router(config-te-mesh-group)# destination-list dl1This example shows how to configure the tunnel affinity and signalled-bandwidth for a path-option:
RP/0/RP0/CPU0:router# config RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# attribute-set path-option myset RP/0/RP0/CPU0:router(config-te-attribute-set)# affinity 0x3 mask 0x3 RP/0/RP0/CPU0:router(config-te-attribute-set)# signalled-bandwidth 2000auto-bw (MPLS-TE)
To configure automatic bandwidth on a tunnel interface and to enter MPLS-TE automatic bandwidth interface configuration mode, use the auto-bw command in MPLS-TE interface configuration mode. To disable the automatic bandwidth on that tunnel, use the no form of this command.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Use the auto-bw command to enter MPLS-TE automatic bandwidth interface configuration mode.
The auto-bw and load-share unequal commands should not be used together.
The load-share unequalcommand determines the load-share for a tunnel based on the bandwidth. However, the MPLS-TE automatic bandwidth feature changes the bandwidth around. If you are configuring both the load-share unequal command and the MPLS-TE automatic bandwidth feature, we recommend that you specify an explicit load-share value configuration under each MPLS-TE automatic bandwidth tunnel.
The following automatic bandwidth scenarios are described:
- If you configure the automatic bandwidth on a tunnel, the automatic bandwidth is enabled on that tunnel. If no other configuration is specified, defaults for the various parameters are used, the operation stops.
- The automatic operation (for example, output rate collection) starts as soon as the automatic bandwidth is enabled on one tunnel. If automatic bandwidth is disabled from all tunnels, the operation stops.
- If the output rate collection is already active when the automatic bandwidth is configured on a tunnel, the statistics collection for that tunnel starts at the next collection configuration.
Note
Because the collection timer is already running, the first collection event for that tunnel happens in less than C minutes (for example, on an average of C/2 minutes).
Task ID
Examples
The following example shows how to enter MPLS-TE automatic bandwidth interface configuration mode:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# auto-bw RP/0/RP0/CPU0:router(config-if-tunte-autobw)#Related Commands
Command
Description
Configures the tunnel-bandwidth change threshold to trigger an adjustment.
Configures the application frequency, in minutes, for the applicable tunnel.
Configures the minimum and maximum automatic bandwidth to set on a tunnel.
Enables only the bandwidth collection without adjusting the automatic bandwidth.
Configures an MPLS-TE tunnel interface.
Configures tunnel overflow detection.
Displays information about MPLS-TE tunnels.
auto-bw collect frequency (MPLS-TE)
To configure the automatic bandwidth collection frequency, use the auto-bw collect frequency command in MPLS-TE configuration mode. To reset the automatic bandwidth frequency to its default value, use the no form of this command.
Syntax Description
minutes
Interval between automatic bandwidth adjustments, in minutes. The range is from 1 to 10080. The default is 5.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
The auto-bw collect frequency command configures the automatic bandwidth collection frequency for all the tunnels.
Modifying the global collection frequency does not restart the tunnel for the current application period. The application period continues with the modified collection frequency.
Task ID
Examples
The following example configures a tunnel for an automatic bandwidth adjustment of 100 minutes:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# auto-bw collect frequency 100autoroute announce
To specify that the Interior Gateway Protocol (IGP) should use the tunnel (if the tunnel is up) in its enhanced shortest path first (SPF) calculation, use the autoroute announce command in interface configuration mode. To return to the default behavior, use the no form of this command.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Currently, the only way to forward traffic over a tunnel is to use the autoroute announce or static routes commands.
When you configure more than one IGP, the tunnel is announced to the IGP used to find the path to the tunnel destination.

mpls traffic-eng interface-path-id auto-tunnel backup
Configures the automatic backup tunnel for a specific interface.
Displays information about MPLS-TE tunnels.
Configures range of tunnel interface numbers for automatic backup tunnels.
backup-bw
To configure the backup bandwidth for an MPLS-TE backup tunnel (that is used to protect a physical interface), use the backup-bw command in interface configuration mode. To return to the default behavior, use the no form of this command.
backup-bw { backup bandwidth { any-class-type | class-type ct } | global-pool { bandwidth | unlimited } | sub-pool { bandwidth | unlimited } | unlimited { any-class-type | class-type ct } }
no backup-bw { backup bandwidth { any-class-type | class-type ct } | global-pool { bandwidth | unlimited } | sub-pool { bandwidth | unlimited } | unlimited { any-class-type | class-type ct } }
Syntax Description
backup bandwidth
Backup bandwidth in any-pool provided by an MPLS-TE backup tunnel. Bandwidth is specified in kilobits per second (kbps). Range is 1 to 4294967295.
any-class-type
Displays the backup bandwidth assigned to any class-type protected tunnels.
class-type ct
Displays the class type of the backup bandwidth. Range is 0 to 1.
global-pool bandwidth
(In Prestandard DS-TE with RDM) Displays the backup bandwidth in global pool provided by an MPLS-TE backup tunnel. Bandwidth is specified in kilobits per second. Range is 1 to 4294967295.
unlimited
Displays the unlimited bandwidth.
sub-pool bandwidth
(In Prestandard DS-TE with RDM) Displays the backup bandwidth in sub-pool provided by an MPLS-TE backup tunnel. Bandwidth is specified in kilobits per second. Range bandwidth is 1 to 4294967295. Only label switched paths (LSPs) using bandwidth from the sub-pool can use the backup tunnel.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Backup bandwidth can be limited or unlimited or specific to a global pool, sub-pool, or non-specific any-pool. Backup with backup-bw in global-pool protects global-pool LSPs only; backup-bw in sub-pool protects sub-pool LSPs only.
Backup tunnels configured with limited backup bandwidth (from any/global/sub pool) are not assigned to protect LSPs configured with zero signaled bandwidth.
Backup bandwidth provides bandwidth protection for fast reroute (FRR). Bandwidth protection for FRR supports DiffServ-TE with two bandwidth pools (class-types).
Class-type 0 is strictly equivalent to global-pool; class-type 1 is strictly equivalent to sub-pool bandwidth using the Russian Doll Model (RDM).
Task ID
Examples
The following example shows how to configure backup tunnel 1 for use only by LSPs that take their bandwidth from the global pool (class-type 0 tunnels). Backup tunnel 1 does not provide bandwidth protection.
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# backup-bw global-pool unlimitedor
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# backup-bw unlimited class-type 0In the following example, backup tunnel 2 is used by LSPs that take their bandwidth from the sub-pool (class-type 1 tunnels) only. Backup tunnel 2 provides bandwidth protection for up to 1000 units.

Syntax Description
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
When the protected interface is down (shut down or removed), the traffic it was carrying (for the other label switched paths [LSPs], referred to as the protected LSPs) is rerouted, using fast reroute (FRR) onto the backup tunnels.
The following guidelines pertain to the FRR process:
- Multiple (backup) tunnels can protect the same interface by entering this command multiple times for different tunnels. The same (backup) tunnel can protect multiple interfaces by entering this command for each interface.
- The backup tunnel used to protect a physical interface must have a valid IP address configured.
- The backup tunnel cannot pass through the same interface that it is protecting.
- TE tunnels that are configured with the FRR option, cannot be used as backup tunnels.
- For the backup tunnel to provide protection to the protected LSP, the backup tunnel must have a terminating-end node in the path of a protected LSP.
- The source IP address of the backup tunnel and the merge point (MP) address (the terminating-end address of the backup tunnel) must be reachable.
Note
You must configure record-route on TE tunnels that are protected by multiple backup tunnels merging at a single node.
Task ID
Examples
The following example shows how to protect PoS interface 0/7/0/0 using tunnel 100 and tunnel 150:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# interface POS 0/7/0/0 RP/0/RP0/CPU0:router(config-mpls-te-if)# backup-path tunnel-te 100 RP/0/RP0/CPU0:router(config-mpls-te-if)# backup-path tunnel-te 150bw-limit (MPLS-TE)
To configure the minimum and maximum automatic bandwidth to be set on a tunnel, use the bw-limit command in MPLS-TE automatic bandwidth interface configuration mode. To disable this feature, use the no form of this command.
Syntax Description
min bandwidth
Configures the minimum automatic bandwidth, in kbps, on a tunnel. The range is from 0 to 4294967295. The default is 0.
max bandwidth
Configures the maximum automatic bandwidth, in kbps, on a tunnel. The range is from 0 to 4294967295. The default is 4294967295.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Both the min and max keywords must be configured.
The bw-limit command automatically sets the minimum bandwidth to the default value of 0, or the bw-limit command automatically sets the maximum to the default value of 4294967295 kbps.
If the value of the min keyword is greater than the max keyword, the bw-limit command is rejected. If you configure and modify the minimum or maximum bandwidth while the automatic bandwidth is already running, the next bandwidth application for that tunnel is impacted. For example, if the current tunnel requested bandwidth is 30 Mbps and the minimum bandwidth is modified to 50 Mbps, the next application sets the tunnel bandwidth to 50 Mbps.

Syntax Description
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
You can configure both the MAM and RDM bandwidth values on a single interface before swapping to an alternate global MPLS-TE BC model.
If you configure bandwidth constraints without configuring the corresponding bandwidth constraint values, the router uses default bandwidth constraint values.
MAM is not supported in prestandard DS-TE mode. MAM and RDM are supported in IETF DS-TE mode; RDM is supported in prestandard DS-TE mode.
Note
Changing the bandwidth constraints model affects the entire router and may have a major impact on system performance as nonzero-bandwidth tunnels are torn down.

The following example shows how to enable the MAM bandwidth constraints model:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# ds-te bc-model mamds-te mode
To configure standard differentiated-service TE mode (DS-TE), use the ds-te mode command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.
Syntax Description
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
The following two DS-TE modes are supported:
- Prestandard mode
- IETF mode
For DS-TE to function properly, DS-TE modes must be configured identically on all MPLS-TE nodes. If you need to change the DS-TE mode, you must bring down all tunnel interfaces and after the change, you should flood the updated bandwidth values through the network.
- Standard defined extensions are used for IGPs and RSVP signalling and DS-TE in this mode interoperates with third-party equipment.
- IETF mode supports two bandwidth constraint models: the Russian Doll Model (RDM) and Maximum Allocation Model (MAM).
- RDM is the default model.
- Router advertises variable-length bandwidth constraints, max-reservable- bandwidth, and unreserved bandwidths in TE-classes.
- tunnels must have valid class-type and priority configured as per TE-class map in use; otherwise, tunnels remain down.
- TE-class map (a set of tunnel priority and class-type values) is enabled to interpret unreserved bandwidth values advertised in IGP; therefore, TE-class map must be identical on all nodes for TE tunnels to be successfully established
Note
Changing the DS-TE mode affects the entire LSR and can have a major impact on system performance when tunnels are torn down.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
In IETF DS-TE mode, modified semantic of the unreserved bandwidth TLV is used. Each of the eight available bandwidth values advertised in the IGP corresponds to a TE class. Because IGP advertises only eight bandwidth values, only eight TE-Classes can be supported in a IETF DS-TE network. The TE-Class mapping must be configured the same way on every router in a DS-TE domain. There is, however, no method to automatically detect or enforce this required consistency.
Task ID

preferred (Optional) Causes the backup tunnel to avoid SRLGs of its protected interface(s); however, the backup tunnel is created if SRLGs are not avoided.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Strict SRLG configuration of this command means that the path computed for the backup tunnel that is automatically created, must not contain any links that are part of the excluded SRLG groups. If such a path cannot be found, the backup tunnel does not come up.
Configuration of the preferred option allows the automatic backup tunnel to come up even if a path that excludes SRLGs can not be found.
Task ID
Examples
In the following example, automatic backup tunnels must avoid SRLGs of the protected interface.
RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# interface pos 0/1/0/1 RP/0/RP0/CPU0:router(config-mpls-te-if)# auto-tunnel backup RP/0/RP0/CPU0:router(config-mpls-te-if-auto-backup)# exclude srlg preferredfast-reroute
To enable fast-reroute (FRR) protection for an MPLS-TE tunnel, use the fast-reroute command in interface configuration mode. To return to the default behavior, use the no form of this command.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
When a protected link used by the fast-reroutable label switched path (LSP) fails, the traffic is rerouted to a previously assigned backup tunnel. Configuring FRR on the tunnel informs all the nodes that the LSP is traversing that this LSP desires link/node/bandwidth protection.
You must allow sufficient time after an switchover before triggering FRR on standby to synchronize with the active (verified using the show redundancy command). All TE tunnels must be in the recovered state and the database must be in the ready state for all ingress and egress line cards. To verify this information, use the show mpls traffic-eng tunnels and show mpls traffic-eng fast-reroute database commands.
Note
Wait approximately 60 seconds before triggering FRR after verifying the database state.
Task ID
Examples
The following example shows how to enable FRR on an MPLS-TE tunnel:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# fast-reroutefast-reroute protect
To enable node and bandwidth protection for an MPLS-TE tunnel, use the fast-reroute protect command in interface configuration mode. To return to the default behavior, use the no form of this command.
Syntax Description
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Task ID
Examples
The following example shows how to enable bandwidth protection for a specified TE tunnel:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)#interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# fast-reroute protect bandwidthfast-reroute timers promotion
To configure how often the router considers switching a protected MPLS-TE tunnel to a new backup tunnel if additional backup-bandwidth or a better backup tunnel becomes available, use the fast-reroute timers promotion command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.
Syntax Description
interval
Interval, in seconds, between scans to determine if a label switched path (LSP) should use a new, better backup tunnel. Range is 0 to 604800. A value of 0 disables backup tunnel promotions.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Setting the interval to a low value puts more load on the CPU because it has to scan all protected LSPs more frequently. It is not recommended that the timer be configured below the default value of 300 seconds.
Pacing mechanisms have been implemented to distribute the load on the CPU when backup promotion is active. Because of this, when a large number of protected LSPs are promoted, some delay is noticeable in backup promotion. If the promotion timer is configured to a very low value (depending on the number of protected LSPs) some protected LSPs may never get promoted.
To disable the timer, set the value to zero.
Task ID
Examples
The following example shows how to specify that LSPs are scanned every 600 seconds (10 minutes) to determine if they should be promoted to a better backup tunnel:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# fast-reroute timers promotion 600flooding thresholds
To set the reserved bandwidth thresholds for a link, use the flooding thresholds command in MPLS-TE interface configuration mode. To return to the default behavior, use the no form of this command.
flooding thresholds { down | up } percent [ percent1 | percent2 | percent3 | ... percent 15 ]
no flooding thresholds { down | up }
Syntax Description
down
Configures the threshold for decreased resource availability.
up
Configures the threshold for increased resource availability.
percent [ percent ]

Command Default
down: 100, 99, 98, 97, 96, 95, 90, 85 , 80, 75 , 60, 45, 30, 15
up: 5, 30, 45, 60, 75, 80, 85, 90, 95, 97 , 98, 99, 100
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
You can configure up to 16 flooding threshold values. The first value is mandatory; the next 15 are optional.
When a threshold is crossed, MPLS-TE link management advertises updated link information. If no thresholds are crossed, changes can be flooded periodically unless periodic flooding was disabled.
Task ID
Examples
The following example shows how to set the reserved bandwidth threshold for the link for decreased resource availability (down) and for increased resource availability (up) thresholds:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# interface POS 0/7/0/0 RP/0/RP0/CPU0:router(config-mpls-te-if)# flooding thresholds down 100 75 25 RP/0/RP0/CPU0:router(config-mpls-te-if)# flooding thresholds up 25 50 100Related Commands
Command

forwarding-adjacency
To configure an MPLS-TE forwarding adjacency, use the forwarding-adjacency command in interface configuration mode. To return to the default behavior, use the no form of this command.
Syntax Description
holdtime time
(Optional) Configures the holdtime value, in milliseconds, that is associated with each forwarding-adjacency LSP. The default is 0.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
If you do not specify a holdtime time value, a delay is introduced with the following results:
- When forwarding-adjacency is configured on a tunnel that is up, TE notifies IGP without any additional delay.
- When forwarding-adjacency is not configured on a tunnel, TE notifies IGP without any additional delay.
- When forwarding-adjacency is configured on a tunnel that is down, TE does not notify IGP.
- When a tunnel on which forwarding-adjacency has been configured comes up, TE holds the notification to IGP for the period of holdtime (assuming nonzero holdtime). When the holdtime elapses, TE notifies IGP if the tunnel is still up.
The paths that traffic is taking to the destination can be manipulated by adjusting the forwarding adjacency link metric. To do that, use the bandwidth command. The unit of possible bandwidth values is in kbps.
Task ID
Examples
This example shows how to configure forwarding adjacency with a holdtime value of 60 milliseconds:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 888 RP/0/RP0/CPU0:router(config-if)# forwarding-adjacency holdtime 60index exclude-address

Syntax Description
index-id
Index number at which the path entry is inserted or modified. Range is 1 to 65535.
ipv4 unicast IP address
Excludes the IPv4 unicast address.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
You cannot include or exclude addresses from an IP explicit path unless explicitly configured using the exclude-address keyword.
Use the exclude-addresskeyword only after entering the explicit path configuration mode.
If you use the exclude-address keyword and specify the IP address of a link, the constraint-based routine does not consider that link when it sets up MPLS-TE paths. If the excluded address is a flooded MPLS-TE router ID, the constraint-based shortest path first (SPF) routine does not consider that entire node.
Note
The person who performs the configuration must know the IDs of the routers, as it may not be apparent if the value refers to the link or to the node.
MPLS-TE accepts IP explicit paths composed of all excluded addresses configured using the exclude-address keyword.

Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
A routers identifier acts as a stable IP address for the TE configuration. This IP address is flooded to all nodes. You must set the destination on the destination node TE router identifier for all affected tunnels. This router ID is the address that the TE topology database at the tunnel head uses for its path calculation.
Note
When the mpls traffic-eng router-id command is not configured, global router ID is used by MPLS-TE if there is one configured.
Task ID
Examples
The following examples show how to specify the TE router identifier as the IP address associated with loopback interface:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# router ospf CORE_AS RP/0/RP0/CPU0:router(config-ospf)# mpls traffic-eng router-id 7.7.7.7 RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# router isis 811 RP/0/RP0/CPU0:router(config-isis)# address-family ipv4 unicast RP/0/RP0/CPU0:router(config-isis-af)# mpls traffic-eng router-id 8.8.8.8mpls traffic-eng repotimize mesh group

Task ID
nhop-only (auto-tunnel backup)
To configure only a next-hop automatic backup tunnel with only link protection, use the nhop-only command in MPLS-TE auto-tunnel backup interface configuration mode. To return to the default configuration setting for automatic backup tunnels, use the no form of this command.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
If you configure the nhop-only command, you destroy any next-next-hop (NNHOP) tunnel created to provide node protection for tunnels running over the specified interface.
If you unconfigure the nhop-only command, you trigger a backup assignment on primary tunnels running over that link. The automatic backup tunnel feature attempts to create NNHOP backup tunnnels to provide node protection for the specified tunnels.
Task ID
Examples
In the following example, NNHOP automatic backup tunnels are destroyed and only NHOP tunnels with link protection is configured:
RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# interface pos 0/1/0/1 RP/0/RP0/CPU0:router(config-mpls-te-if)# auto-tunnel backup RP/0/RP0/CPU0:router(config-mpls-te-if-auto-backup)# nhop-onlyoverflow threshold (MPLS-TE)
To configure the tunnel overflow detection, use the overflow threshold command in MPLS-TE automatic bandwidth interface configuration mode. To disable the overflow detection feature, use the no form of this command.
Syntax Description
percentage
Bandwidth change percent to trigger an overflow. The range is from 1 to 100.
min bandwidth
(Optional) Configures the bandwidth change value, in kbps, to trigger an overflow.
The range is from 10 to 4294967295. The default is 10.
limit limit
Configures the number of consecutive collection intervals that exceeds the threshold. The bandwidth overflow triggers an early tunnel bandwidth update.
The range is from 1 to 10. The default is none.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
If you modify the limit keyword, the consecutive overflows counter for the tunnel is also reset.
If you enable or modify the minimum value, the current consecutive overflows counter for the tunnel is also reset, which effectively restarts the overflow detection from scratch.
Several number of consecutive bandwidth samples are greater than the overflow threshold (bandwidth percentage) and the minimum bandwidth configured, then a bandwidth application is updated immediately instead of waiting for the end of the application period.
Overflow detection applies only to bandwidth increase. For example, an overflow can not be triggered even if bandwidth decreases by more than the configured overflow threshold.
Task ID
Examples
The following example shows how to configure the tunnel overflow detection for tunnel-te 1:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# auto-bw RP/0/RP0/CPU0:router(config-if-tunte-autobw)# overflow threshold 50 limit 3Related Commands

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
You can configure several path options for a single tunnel. For example, there can be several explicit path options and a dynamic option for one tunnel. The path setup preference is for lower (not higher) numbers, so option 1 is preferred.
When the lower number path option fails, the next path option is used to set up a tunnel automatically (unless using the lockdown option).
You specify the backup path for the path-option command in case of the primary path failure.
CSPF areas are configured on a per-path-option basis.
Task ID
Examples
The following example shows how to configure the tunnel to use a named IPv4 explicit path as verbatim and lockdown options for the tunnel. This tunnel cannot reoptimize when the FRR event goes away, unless you manually reoptimize it:

Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
You can configure several path options for each destination of a P2MP tunnel. For example, for one tunnel, there can be several explicit path options and a dynamic option. The path preference is for lower (not higher) numbers, so option 1 is preferred over higher options.
When the lower number path option fails, the next path option under the destination is attempted.
Several path-options can be configured for each destination under a tunnel.
When configuring multiple path-options under each destination of a P2MP tunnel, the PCALC on the TE tunnel source attempts to generate the P2MP tree starting from the preferred path-options (lower numbers) for each destination. If some destinations use explicit paths that cause remerges with the dynamic generated paths for other destinations in the P2MP tree, the PCALC source modifies the dynamic paths (for example, optimal path); therefore, it follows the explicit path to correct the remerge problem.
The path-option command is common for both Point-to-Point (P2P) and P2MP tunnels.
Task ID
Examples
This example shows how to configure a P2MP tunnel with two destinations and several path-options per destination:
RP/0/RP0/CPU0:router(config)# interface tunnel-mte 100 RP/0/RP0/CPU0:router(config-if)# destination 1.1.1.1 RP/0/RP0/CPU0:router(config-if-p2mp-dest)# path-option 1 explicit name po_dest1 RP/0/RP0/CPU0:router(config-if-p2mp-dest)# path-option 2 dynamicThis example shows that the fallback path option is dynamic:

Command History
Release
Modification
Release 4.1.0
The head, mid, and tail keywords were added.
Release 5.0.0 This command was introduced.
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Use the path-selection ignore overload command to ensure that label switched paths (LSPs) are not broken because of routers that have IS-IS overload bit as enabled.
When the IS-IS overload bit avoidance (OLA) feature is activated, all nodes with the overload bit set, which includes head nodes, mid nodes, and tail nodes, are ignored. This means that they are still available for use with label switched paths (LSPs). This feature allows you to include an overloaded node in constraint-based shortest path first (CSPF).

priority (MPLS-TE)
To configure the setup and reservation priority for an MPLS-TE tunnel, use the priority command in interface configuration mode. To return to the default behavior, use the no form of this command.
Syntax Description
setup-priority
Priority used when signaling a label switched path (LSP) for this tunnel to determine which existing tunnels can be preempted. Range is 0 to 7 (in which a lower number indicates a higher priority). Therefore, an LSP with a setup priority of 0 can preempt any LSP with a non-0 priority.
hold-priority
Priority associated with an LSP for this tunnel to determine if it should be preempted by other LSPs that are being signaled. Range is 0 to 7 (in which a lower number indicates a higher priority).
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
When an LSP is signaled and an interface does not currently have enough bandwidth available for that LSP, the call admission software (if necessary) preempts lower-priority LSPs to admit the new LSP. Accordingly, the new LSP priority is the setup priority and the existing LSP priority is the hold priority. The two priorities make it possible to signal an LSP with a low setup priority (so that the LSP does not preempt other LSPs on setup) and a high hold priority (so that the LSP is not preempted after it is established). Setup priority and hold priority are typically configured to be equal, and setup priority cannot be numerically smaller than the hold priority.

no reoptimize timers delay { after-frr seconds | cleanup delay-time | installation delay-time | path-protection seconds }
Syntax Description
after-frr
Delays the LSP reoptimization in the event of the FRR.
seconds
Reoptimization initiation delay time of the tunnel, in seconds, after an FRR event. Range is from 0 to 120.
cleanup
Delays removal of the old LSPs after tunnel reoptimization.
delay-time
Reoptimization delay time, in seconds. A value of 0 disables delay. The valid range is from 0 to 300 for cleanup time.
installation
Delays installation of a new label after tunnel reoptimization.
delay-time
Reoptimization delay time, in seconds. A value of 0 disables delay. The valid range is 0 to 3600 for installation time.
path-protection
Delays the time between path protection switchover event and tunnel reoptimization.
seconds
Time, in seconds, between path protection switchover event and tunnel reoptimization. A value of 0 disables delay. Range is from 0 to 604800.
Command Default
after-frr delay: 0
cleanup delay: 20
delay-time: 20
installation delay: 20
path-protection: 180
Command History
Usage Guidelines
A device with Multiprotocol Label Switching traffic engineering (MPLS-TE) tunnels periodically examines tunnels with established LSPs to discover whether more efficient LSPs (paths) are available. If a better LSP is available, the device signals the more efficient LSP; if the signaling is successful, the device replaces the older LSP with the new, more efficient LSP.
Sometimes the slower router-point nodes may not yet utilize the new label’s forwarding plane. In this case, if the headend node replaces the labels quickly, it can result in brief packet loss. By delaying the cleanup of the old LSP using the reoptimize timers delay cleanup command, packet loss is avoided.
Task ID
Examples
The following example shows how to set the reoptimization cleanup delay time to 1 minute:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# reoptimize timers delay cleanup 60The following example shows how to set the reoptimization installation delay time to 40 seconds:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# reoptimize timers delay installation 40The following example shows how to set the reoptimization delay time after the event of the FRR to 50 seconds:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# reoptimize timers delay after-frr 50The following example shows how to set the reoptimization delay time between path protection switchover event and tunnel reoptimization to 80:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# reoptimize timers delay path-protection 80router-id secondary (MPLS-TE)

Usage Guidelines
You must be in a user group associated with a task group that includes the proper task IDs. The command reference guides include the task IDs required for each command. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Use the brief form of the show mpls traffic-eng tunnels command to display information specific to a tunnel interface. Use the command without the brief keyword to display information that includes the destination address, source ID, role, name, suboptimal constraints, and interface.
The affinity keyword is available for only the source router.
Selected tunnels would have a shorter path if they were reoptimized immediately.
Task ID
Examples
This sample output is not changed when no area is specified for the active path-option. If the area is specified, it is added on a line of its own after the existing path-option information.

To configure the bandwidth required for an MPLS-TE tunnel, use the signalled-bandwidth command in interface configuration mode. To disable the behavior, use the no form of this command.
signalled-bandwidth { bandwidth [ class-type ct ] | sub-pool bandwidth }
no signalled-bandwidth { bandwidth [ class-type ct ] | sub-pool bandwidth }
Syntax Description
bandwidth
Bandwidth required for an MPLS-TE tunnel. Bandwidth is specified in kilobits per second. By default, bandwidth is reserved in the global pool. Range is from 0 to 4294967295.
class-type ct
(Optional) Configures the class type of the tunnel bandwidth request. Range is from 0 to 1. Class-type 0 is strictly equivalent to global-pool. Class-type 1 is strictly equivalent to subpool.
sub-pool bandwidth
Reserves the bandwidth in the subpool instead of the global pool. Range is 1 to 4294967295. A subpool bandwidth value of 0 is not allowed.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
The signalled-bandwidth command supports two bandwidth pools (class-types) for the Diff-Serv Aware TE (DS-TE) feature.
Note
The Cisco Diff-Serve Aware TE feature is compliant to IETF standard and will interoperate with third party vendor DS-TE. Both Russian Doll Model and Maximum Allocation Model for bandwidth allocation are supported. We recommended that IETF terminology be used in DS-TE bandwidth configurations, namely, Class-type (CT) and Bandwidth Constraints (BC).
Task ID
Examples
This example shows how to set the bandwidth required for an MPLS-TE tunnel to 1000 in the global pool (class-type 0):
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# signalled-bandwidth 1000 RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# signalled-bandwidth 1000 class-type 0This example shows how to set the bandwidth required for an MPLS-TE tunnel to 1000 in the sub-pool (class-type 1):
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# signalled-bandwidth sub-pool 1000 RP/0/RP0/CPU0:router(config)# interface tunnel-te 1 RP/0/RP0/CPU0:router(config-if)# signalled-bandwidth 1000 class-type 1signalled-name
To configure the name of the tunnel required for an MPLS-TE tunnel, use the signalled-name command in interface configuration mode. To return to the default behavior, use the no form of this command.

To specify that tunnels terminating on a router use explicit-null labels, use the signalling advertise explicit-null command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Use the signalling advertise explicit-null command to specify that tunnels terminating on this router use explicit-null labels. This command applies to tunnel labels advertised to next to last (penultimate) hop.
The explicit label is used to carry quality-of-service (QoS) information up to the terminating-end router of the label switched path (LSP).
Task ID
Examples
The following example shows how to configure explicit null tunnel labels:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# signalling advertise explicit-nullsnmp traps mpls traffic-eng
To enable the router to send Multiprotocol Label Switching traffic engineering (MPLS-TE) Simple Network Management Protocol (SNMP) notifications or informs, use the snmp traps mpls traffic-eng command in global configuration mode. To disable this behavior, use the no form of this command.

The preempt keyword was added.
Release 5.0.0 This command was introduced.
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
If the command is entered without the notification-option argument, all MPLS-TE notification types are enabled.
SNMP notifications can be sent as either traps or inform requests.
The snmp-server enable traps mpls traffic-eng command enables both traps and inform requests for the specified notification types. To specify whether the notifications should be sent as traps or informs, use the snmp-server host command and specify the keyword trap or informs.
If you do not enter the snmp traps mpls traffic-eng command, no MPLS-TE notifications controlled by this command are sent. To configure the router to send these MPLS-TE SNMP notifications, you must enter at least one snmp enable traps mpls traffic-eng command. If you enter the command with no keywords, all MPLS-TE notification types are enabled. If you enter the command with a keyword, only the notification type related to that keyword is enabled. To enable multiple types of MPLS-TE notifications, you must issue a separate snmp traps mpls traffic-eng command for each notification type and notification option.
The snmp traps mpls traffic-eng command is used in conjunction with the snmp host command. Use the snmp host command to specify which host or hosts receive MPLS-TE SNMP notifications. To send notifications, you must configure at least one snmp host command.
For a host to receive an MPLS-TE notification controlled by this command, both the snmp traps mpls traffic-eng command and the snmp host command for that host must be enabled.
Task ID

Modification
Release 4.0.0
The value argument was added. Command mode was changed to the global configuration mode.
Release 5.0.0 This command was introduced.
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
You can enter up to 30 SRLG entries on the ingress and egress ports of the interface. SRLG entries configured over 30 are silently dropped.
Task ID
Examples
The following example shows how to configure an SRLG with 10 member links:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router#(config)# srlg RP/0/RP0/CPU0:router#(config-srlg)# interface POS 0/3/0/2 RP/0/RP0/CPU0:router#(config-srlg-if)# value 10timers loose-path (MPLS-TE)
To configure the period between the headend retries after path errors, use the timers loose-path command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.
Syntax Description
retry-period value
Configures the time, in seconds, between retries upon a path error. Range is 30 to 600.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Task ID
Examples
The following example shows how to the period between retries after path errors to 300 seconds:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# timers loose-path retry-period 300timers removal unused (auto-tunnel backup)
To configure the frequency at which a timer scans backup autotunnels and removes tunnels that are not in use, use the timers removal unused (auto-tunnel backup)command in auto-tunnel backup configuration mode. To return to the default behavior, use the no form of this command.
Syntax Description
frequency Frequency, in minutes, between backup autotunnel scans to remove tunnels that are not used. Range is 0; 5 to 10080 minutes (7 days). A value of 0 disables the scanning and removal of tunnels.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
The unused auto-tunnel backup tunnel is the tunnel that is not assigned to protect any FRR tunnel.
Task ID
Examples
The following example shows that unused automatic backup tunnels are removed after the 10 minute timer scan is reached.
RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# auto-tunnel backup RP/0/RP0/CPU0:router(config-te-auto-bk)# timers removal unused 10timeout (soft-preemption)
To override the soft-preemption default timeout, use the timeout command in MPLS TE mode. To remove this configuration, use the no form of this command.
Syntax Description
timeout seconds Defines the timeout for soft-preempted LSP, in seconds. The default timeout is 60. Range is from 30 to 300.
Command History
Usage Guidelines
You must be in a user group associated with a task group that includes the proper task IDs. The command reference guides include the task IDs required for each command. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Task ID
topology holddown sigerr (MPLS-TE)
To specify the time that a router should ignore a link in its TE topology database in tunnel path constrained shortest path first (CSPF) computations following a TE tunnel signaling error on the link, use the topology holddown sigerr command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.
Syntax Description
seconds
Time that the router ignores a link during tunnel path calculations, following a TE tunnel error on the link, specified in seconds. Range is 0 to 300. Default is 10.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
A router at the headend for TE tunnels can receive a Resource Reservation Protocol (RSVP) No Route error message before the router receives a topology update from the IGP routing protocol announcing that the link is down. When this happens, the headend router ignores the link in subsequent tunnel path calculations to avoid generating paths that include the link and are likely to fail when signaled. The link is ignored until the router receives a topology update from its IGP or a link holddown timeout occurs. Use the topology holddown sigerr command to change the link holddown time from its 10-second default value.
Task ID
Examples
The following example shows how to set the link holddown time for signaling errors at 15 seconds:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# topology holddown sigerr 15tunnel-id (auto-tunnel backup)
To configure the range of tunnel interface numbers to be used for automatic backup tunnels, use the tunnel-id command in auto-tunnel backup configuration mode. To delete the automatic backup tunnels, use the no form of this command.
Syntax Description
min (Optional) Minimum number for automatic backup tunnels.
number Valid values are from 0 to 65535.
max (Optional) Maximum number for automatic backup tunnels.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
If you increase the tunnel ID range, the automatic backup tunnels that failed earlier will get created the next time automatic backup assignments are processed.
Restrictions:
- Command is rejected if the max value minusmin value is >= 1K.
- Command is rejected if min value > max value.
- Command is rejected if min value is greater than the tunnel ID of an existing automatic backup tunnel.
- Command is rejected if max value is smaller than the tunnel ID of an existing automatic backup tunnel.
- Command is rejected if a statically configured tunnel ID matches with the configured min and max range of values.
- Command is rejected if a static backup assignment is already configured to a tunnel with an ID within the min value /max value range.
Task ID
Examples
The following example allows 800 automatic backup tunnels to be created:
RP/0/RP0/CPU0:router(config)# mpls traffic-eng RP/0/RP0/CPU0:router(config-mpls-te)# auto-tunnel backup RP/0/RP0/CPU0:router(config-te-auto-bk)# tunnel-id min 1200 max 2000
