Understanding Multiprotocol Label Switching Transport Profile
Multiprotocol Label Switching Transport Profile (MPLS–TP) is a carrier–grade packet transport technology that enables service providers to move from Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH) time–division multiplexing (TDM) to packet switching. MPLS–TP enables MPLS to be deployed in a transport network to support packet transport services with a similar degree of predictability to that found in existing transport networks.
The goal of MPLS–TP is to provide connection–oriented transport for packet and TDM services over optical networks leveraging the widely deployed MPLS
technology. Operations, Administration, and Maintenance (OAM) and resiliency features are defined and implemented in MPLS–TP to ensure the capabilities needed for carrier–grade packet
transport networks—scalable operations, high availability, performance monitoring and multidomain support.
MPLS–TP defines a profile of MPLS targeted at transport applications and networks. This profile specifies the MPLS characteristics and extensions required to meet the transport requirements.
Note
MPLS–TP supports only point–to–point Layer 2 VPN service in this release. The point–to–point Layer 2 VPN service is called Virtual Private Wire Service (VPWS). MPLS–TP supports only static pseudowires in this release.
Key Features
The key features of MPLS–TP are as follows:
Connection–oriented.
Carries Layer 3 and Layer 2 services.
Runs over IEEE Ethernet PHYs, OTN, WDM and so on.
Static and bidirectional label-switched path (LSP) provisioning.
OAM functions similar to those available in traditional optical transport networks such as SONET or SDH are provided. These OAM functions belong to the MPLS–TP data plane and are independent from the control plane.
Fault propagation through Bidirectional Fault Detection (BFD), Link Down Indication (LDI), and Lockout Request (LKR) messages.
1:1 revertive path protection.
IP–less provisioning of tunnels.
Network provisioning through CTC.
Traffic switchover time from working LSP to protect LSP and vice versa is up to 50 milliseconds.
Planes in MPLS–TP
The three planes in MPLS–TP perform the following functions:
Plane
Functions
Control plane through CTC
Constraint-based path computation
Primary and backup LSPs definition
Auto-discovery of existing tunnels
Fault management
Data plane
Forwards data packets
Management plane
Configuration
The control plane is decoupled from the data plane such that the failures in the control plane do not affect the data plane and vice versa.
Restrictions
The following restrictions apply to MPLS–TP:
Penultimate hop popping is not supported. Only ultimate hop popping is supported, because the label mappings are configured at the MPLS–TP end points.
MPLS–TP link numbers are not configured on the interfaces for which Multiprotocol Label Switching Traffic Engineering (MPLS-TE) is enabled and vice versa.
IPv6 addressing is not supported.
Understanding MPLS–TP Operations, Administration, and Maintenance
Several Operations, Administration, and Maintenance (OAM) protocols and messages support the provisioning and maintenance of MPLS–TP tunnels and bidirectional LSPs. The OAM messages are used for fault management, connection verification, continuity check, and other functions. The timers can be configured for each OAM message.
The following OAM messages are forwarded along the specified LSP:
OAM fault management—Link Down Indication (LDI) and Lockout Request (LKR) messages
OAM connection verification—ping and traceroute messages
OAM continuity check—Bidirectional Fault Detection (BFD) messages. min_tx and min_rx are 4 milliseconds.
The following messages are forwarded along the specified pseudowire:
Static pseudowire OAM messages
Pseudowire ping and traceroute messages
Pseudowire BFD messages. min_tx and min_rx are 50 milliseconds.
LDI and LKR Messages
The LDI messages are generated at midpoint nodes when a link failure is detected. The LKR messages are sent from a midpoint node to the reachable endpoint when an interface is administratively shut. When a lockout command is configured on either the working or the protect LSP, an LDI message is sent from the local endpoint to the remote endpoint.
LSP Ping and Trace Messages
For MPLS–TP connectivity verification, ping mpls tp and trace mpls tp commands can be used to specify that the echo requests must be sent along the working LSP or the protect LSP, or the locked out working or protect LSP.
BFD Messages
BFD sessions running on MPLS-TP LSPs can be configured. These sessions run on both the working LSP and the protect LSP. BFD provides continuity check for MPLS–TP LSPs to detect forwarding failures between two adjacent routers. When BFD is enabled on an MPLS–TP tunnel interface, the MPLS–TP client creates separate BFD sessions for working and protect LSPs. A single set of BFD timers is configured on the tunnel that applies to both the working and protect LSPs.
Multiprotocol Label Switching Transport Profile Configuration Procedures
The following procedures can be performed using Cisco IOS commands to configure MPLS–TP:
Specifies the maximum time between successive fault OAM messages specified in seconds. The valid range is from 1 to 255. The default value is 20.
Step 7
wtr-timerseconds
Example:Router(config-mpls-tp)# wtr-timer 25
Specifies the wait-to-restore (WTR) timer. This timer controls the length of time to wait before reverting to the original working path following the repair of a fault on the original working path. The valid range is from 0 to 2147483647.
Step 8
exit
Example:Router(config-mpls-tp)# exit
Returns the router to global configuration mode.
Step 9
Return to your originating procedure (NTP).
Example:—
Example: Configure Global Settings for MPLS–TP
The following example shows how to configure the global settings for MPLS–TP using Cisco IOS commands:
Example:Router(config)# mpls label range 1000 8000 static 16 999
Specifies the static label range that applies to both the pseudowire and MPLS–TP tunnel. The valid range of static and dynamic labels is from 16 to 8000.
The dynamic label range is automatically calculated based on the values specified in the static label range.
Step 4

The static label range specified in the static label applies to both the pseudowire and MPLS–TP tunnel. The valid range of static and dynamic labels is from 16 to 8000. You do not need to specify the values for dynamic labels. The dynamic label range is automatically calculated by CTC based on the values specified in the static label range. For example, if you choose 100 to 1000 for static labels, the dynamic label range is set to 1001 to 8000.
Step 8
Click Apply to specify the static label range.
Step 9
Return to your originating procedure (NTP).
Understanding Bidirectional Forwarding Detection
Bidirectional Forwarding Detection (BFD) provides a low–overhead, short–duration method of detecting failures in the forwarding path between two adjacent routers, including interfaces, data links, and forwarding planes.
BFD is a fault detection protocol that is enabled at the interface level. The BFD asynchronous mode, which depends on sending of BFD control packets between two systems to activate and maintain BFD neighbor sessions between routers, is supported. Therefore, to create a BFD session, BFD must be configured on both systems (or BFD peers). When BFD is enabled on the interfaces, a BFD session is created, BFD timers are negotiated, and the BFD peers begin to send BFD control packets to each other at the negotiated interval.
BFD provides continuity check for MPLS–TP LSPs to detect forwarding failures between two adjacent routers. When BFD is enabled on the MPLS–TP tunnel interface, MPLS–TP client creates separate BFD sessions for working and protect LSPs. A single set of BFD timers is configured on the tunnel that applies to both the working and protect LSPs.
Creates a BFD template and enters BFD configuration mode.
The bfd-template command allows you to create a BFD template and enters BFD configuration mode. The template can be used to specify a set of BFD interval values. You can then invoke the BFD template when you set up the MPLS–TP tunnel.
Example:Router(config-bfd)# interval microseconds both 3300 multiplier 3
Configures the transmit and receive intervals in microseconds between BFD packets, and specifies the number of consecutive BFD control packets that must be missed from a BFD peer before BFD declares that a peer is unavailable.
Example:Router(config-bfd)# interval both 120 multiplier 3
Configures the transmit and receive intervals in milliseconds between BFD packets, and specifies the number of consecutive BFD control packets that must be missed from a BFD peer before BFD declares that a peer is unavailable.
Step 6
exit
Example:Router(config-bfd)# exit
Exits BFD configuration mode and returns the router to global configuration mode.

Understanding Multiprotocol Label Switching Transport Profile Link Numbers
The MPLS–TP link numbers are configured only on the physical interfaces. Only one MPLS–TP link number can be configured for each interface. The user-assigned link numbers must be unique within the router. The show mpls tp link-number command shows all the configured links on the router.
The MPLS–TP link numbers are not assigned to bundled interfaces and virtual interfaces.
The MPLS–TP link numbers can be configured either using the next hop IP address or the MAC address. The valid range of MPLS–TP link number is from 1 to 10000.
When you configure a MPLS–TP link using an IP address for the next hop, you use the following commands, where 209.165.200.226 is the IP address of the next hop router:
interface TenGigabitEthernet4/1ip address 209.165.200.225 255.255.255.0mpls tp link 1 ipv4 209.165.200.226
Transport networks usually do not use IP addresses. You can configure MPLS–TP with links that do not require IP addresses. Instead, Ethernet MAC addresses are used to establish MPLS adjacency between the nodes on Ethernet links. MPLS–TP uses IP only to determine the MAC address of the next hop device through Address Resolution Protocol (ARP).
When you configure a MPLS–TP link without an IP address, you use the following commands:
Router(config)# interface TenGigabitEthernet4/1
Router(config-if)# medium p2p
Router(config-if)# mpls tp link 1
You can use these commands whether the interface has an IP address or not. However, the commands are primarily used when the router and its neighbor router do not have IP addresses.
The medium p2p command changes an interface that allows multiple connections to a point-to-point interface. This command allows the router to send and receive all the MPLS-TP packets using a common multicast MAC address knowing that it is communicating with only one other device.
An interface that is natively point-to-point, such as serial, does not require the medium p2p command.
Alternatively, you can configure the unicast MAC address of the next-hop device as follows:
Router(config)# interface TenGigabitEthernet4/1
Router(config-if)# medium p2p
Router(config-if)# mpls tp link 1 tx-mac 0000.0c00.1234
You can also configure to transmit and receive on some other multicast address as follows:
Router(config)# interface TenGigabitEthernet4/1
Router(config-if)# medium p2p
Router(config-if)# mpls tp link 1 tx-mac 0100.0c99.8877 rx-mac 0100.0c99.8877
Note
When a MPLS–TP link is configured without an IP address on an Ethernet interface, Cisco uses an IEEE Bridge Group MAC address (0180.c200.0000) for communication by default.

Example: Router(config-if)# ip address 209.165.200.225 255.255.255.0
Assigns an IP network address and network mask to the interface.
Step 5
ip rsvp bandwidthvalue
Example: Router(config-if)# ip rsvp bandwidth 100
Enables Resource Reservation Protocol (RSVP) for IP on this interface.
If you configure non-zero bandwidth for the MPLS–TP tunnel or at a midpoint LSP, ensure that the interface to which the output link is attached has enough available bandwidth. For example, if three tunnel LSPs run over link 1 and each LSP was assigned 1000 with the tp bandwidth command, the interface associated with link 1 needs bandwidth of 3000 with the ip rsvp bandwidth command.
Example:Router(config-if)# mpls tp link 1 ipv4 209.165.200.226
Configures the MPLS–TP link either with the IPv4 address of the next hop router or using a per-interface transmit multicast MAC address.
The link-num is a number assigned to the link. It must be unique to the device. Only one link number can be assigned per interface. The valid range is from 1 to 10000.

Example:Router(config-if)# mpls tp link 1 tx-mac 0000.0c00.1234
Configures an MPLS–TP link without the IP address. The tx-mac keyword is available on Ethernet interfaces, but the interface must be point-to-point to configure the value of tx-mac as a multicast MAC address. The rx-mac keyword is available only when the tx-mac keyword is used and only when the interface is point-to-point.

Understanding Multiprotocol Label Switching Transport Profile Tunnels
An MPLS–TP tunnel consists of a pair of unidirectional tunnels providing a bidirectional LSP. Each unidirectional tunnel can be protected with a protect LSP that activates automatically upon failure. MPLS–TP tunnels are provisioned manually at their endpoints across the network.
Tunnel Identifiers
MPLS–TP tunnel identifiers uniquely identify an MPLS–TP tunnel within the network. The tunnel identifier consists of a global identifier, a node identifier,
and a tunnel number for each endpoint of the MPLS–TP LSP.
The node identifier is an IP address for an interface on the endpoint router. The tunnel number is the tunnel–tp number assigned when the tunnel–tp virtual interface is created on the endpoint router.
Tunnel Source
The tunnel source is the MPLS–TP node identifier of the endpoint router that is configured. This tunnel source can be specified to override the router-id configured in the global MPLS-TP configuration.
Tunnel Destination
The tunnel destination is the MPLS–TP node identifier of the remote endpoint router. The destination tunnel number is the virtual interface number assigned to the remote tunnel interface when it is provisioned. This destination tunnel number can be optionally configured. If the destination tunnel number is not configured, it defaults to the local tunnel number.
MPLS–TP LSPs are bidirectional and corouted and are comprised of two unidirectional LSPs that are supported by the MPLS forwarding infrastructure. The static and bidirectional MPLS–TP LSPs can be configured either through CTC or Cisco IOS commands. The LSPs are configured and managed without a control plane. The MPLS–TP LSPs have a fixed path. The statically defined LSP does not require an Interior Gateway Protocol (IGP).
Figure 1. MPLS–TP LSP
MPLS–TP LSPs are not supported over a Link Aggregation Group (LAG). The static pseudowire is the only traffic carried over MPLS–TP LSPs in this release.
LSP Path Protection
MPLS–TP LSPs support 1:1 revertive path protection. The working and protect LSPs can be configured as part of configuring MPLS–TP tunnels. The working LSP is the primary LSP used to route the traffic. The protect LSP is a backup for the working LSP. When the working LSP fails, the traffic is switched to the protect LSP until the working LSP is restored, at which time the forwarding reverts to the working LSP.
LSP Number
The LSP number is assigned when the MPLS–TP LSP
is configured. The default value of the LSP number is 0 for the working LSP and 1 for the protect LSP. You can edit LSP numbers.
LSP Ping and Trace
The LSP ping and trace commands are supported on MPLS–TP bidirectional LSPs and pseudowires.
LSP Lockout
The working LSP or protect LSP can be locked out. Only one LSP must be locked out at a time. When the LSP is currently locked out, the lockout command is not available in the other LSP configuration submode. The lockout of a working or protect LSP is
cleared using the no lockout command.
When the LSP is locked out, the user traffic is not forwarded over the locked out LSP. However, the OAM traffic and BFD traffic is forwarded over the locked out LSP.
Because an MPLS-TP tunnel is statically configured, the possibility exists that the working LSP could be locked out at one MPLS-TP tunnel endpoint and the protect LSP could be locked out at the other MPLS-TP tunnel endpoint. If this occurs, the MPLS-TP tunnel is deadlocked and non-functional until the lockout configuration is changed at one of the endpoints.
LSP Shutdown
When the LSP is shut down, the LDI messages, user traffic, and OAM traffic are not sent.
Tunnel Midpoints and Endpoints
Tunnel LSPs, whether endpoint or midpoint, use the same identifying information. However, it is entered differently.
At the midpoint, all the information for the LSP is specified with the mpls tp lsp command, which enters the submode for configuring forward and reverse information for forwarding.
At the midpoint, determining which end is source and which end is destination is arbitrary. That is, if you are configuring a tunnel between your router and a coworker’s router, your router is the source. However, your coworker considers his or her router to be the source. At the midpoint, either router could be considered the source. At the midpoint, the forward direction is from source to destination, and the reverse direction is from destination to source.
At the endpoint, the source information comes either from the global router ID or from locally configured information using the tp source command after you enter the command interface tunnel-tpnumber command, where number is the source tunnel number.
At the endpoint, the remote information (destination) is configured using the tp destination command after you enter the command interface tunnel-tpnumber. The tp destination command includes the destination node ID, optionally the global ID, and optionally the destination tunnel number. If you do not specify the destination tunnel number, the source tunnel number is used.
At the endpoint, the LSP number is configured in working-lsp or protect-lsp submode. The default value is 0 for the working LSP and 1 for the protect LSP.

The tunnel-tp is the tunnel–TP number of the MPLS–TP tunnel destination. If the tunnel–TP number is not specified, the number assigned to the local tunnel is used.
The global-id is the default global ID used for the endpoint. The default value of the global–id is 0. The valid range is from 0 to 2147483647.
Step 8
bfdbfdtemplatename
Example:Router(config–if)# bfd bfd1
Configures a BFD template for the MPLS–TP tunnel. The BFD configuration template used for the working LSP is the same as that of the protect LSP.
Assigns an outgoing label and outgoing link to the protect LSP. The outgoing label must be a valid and unreserved MPLS label.
A protect LSP is a backup for a working LSP. If the working LSP fails, the traffic is switched to the protect LSP until the working LSP is restored, when forwarding reverts to the working LSP.
Step 16
in–labellocallabelnumber
Example:Router(config–if–protect)# in–label 20
Assigns an incoming label (local label) to the protect LSP. The values for the incoming label must be within the static label range that is defined.
Step 17
lsp–numnumber
Example:Router(config–if–protect)# lsp–num 1
Configures the LSP number for the protect LSP.
The default LSP number for the protect LSP is 1. The range is 1 and above. The local and remote LSP numbers must match.
Step 18
lockout
Example:Router(config–if–protect)# lockout
Locks out the protect LSP.
Step 19
shutdown
Example:Router(config–if)# shutdown
Performs an administrative shut down of the MPLS–TP tunnel.
Step 20
Return to your originating procedure (NTP).
Example: Configuring Tunnel Endpoints
The following example shows how to configure one of the endpoints of the MPLS–TP tunnel using Cisco IOS commands:
You cannot
create an MPLS–TE tunnel and an MPLS–TP tunnel on the same interface.
Note
The layer 2
services on CPT can be created on top of layer 2 PPCs or OCHTrails.
CPT supports
Client/Trunk to Client/Trunk (layer 2) PPC for topology discovery and layer 2
service routing. If CPT is used in the GNE-ENE mode of configuration, then
generic communications channels (GCC) can be used for topology discovery and
layer 2 PPCs for layer 2 service routing. Both layer 2 PPC and GCC can be
created between the same set of ports. However, this is not mandatory.
CPT also
supports OCH Trunk to OCH Filter PPCs to connect CPT to MSTP nodes. If you want
to route the traffic from a non co-located CPT node to a DWDM network, use OCH
Trunk to OCH Filter PPCs to connect CPT and MSTP nodes. The OCHTrail can be
created on top of this and the layer 2 services can be created on top of
OCHTrails.
Procedure
Step 1
Complete the
NTP-J22 Log into CTC procedure at a node on the network
where you want to create an MPLS–TP tunnel.
Step 2
From the View
menu, choose
Go to
Network View.
Step 3
Click the
Layer2+ tab.
Step 4
In the left
pane, click
Circuits.
Step 5
Click the
MPLS TP
Tunnels tab.
Step 6
Click
Create. The Circuit Creation wizard appears.
Step 7
In the Circuit
Attributes screen of the wizard:
Enter the
name of the tunnel that you want to create, in the Name field.
Enter the
description of the tunnel in the Description field.
The type
of the tunnel is MPLS_TP and cannot be changed. The tunnel is always created as
a bidirectional tunnel.
Check the
Protection check box to create a protected tunnel.
From the
Admin State drop–down list, choose
UP or
DOWN . The default value is UP.
Enter the
bandwidth of the MPLS–TP tunnel in Kbps (default), Mbps, or Gbps and click
Next.
Step 8
In the Source
screen of the wizard, specify the parameters for one endpoint:
From the
drop–down list, choose a
.
From the
Attach BFD drop-down list, choose a BFD template to attach to this endpoint.
Note
It is
recommended that the same BFD template be attached for the endpoints.
Enter the
unique tunnel number for this endpoint in the Tunnel Number field.
Enter the
LSP number for the working LSP in the Working LSP Number field. The default
value is 0.
Enter the
LSP number for the protect LSP in the Protect LSP Number field. The default
value is 1. Click
Next.
Step 9
In the
Destination screen of the wizard, specify the parameters for another endpoint.
Repeat the previous step to do this.
Step 10
In the TP Tunnel
Circuit Routing Preferences screen of the wizard, specify the routing
preferences for the tunnel:
For
constraint–based routing, check the
Using
Required Nodes/Spans check box. The
Route
Automatically check box is set by default and cannot be changed.
Specify
the diversity constraints by choosing
Nodal
Diversity Required,
Nodal
Diversity Desired, or
Link
Diversity Only.
Nodal
Diversity Required—Ensures that the primary and alternate paths within path
protection portions of the complete circuit path are nodally diverse.
Nodal
Diversity Desired—Specifies that node diversity is preferred, but if node
diversity is not possible, CTC creates fiber-diverse paths for the path
protection portion of the complete circuit path.
Node
diversity is not applicable if the source and destination are directly
connected with fiber diverse path.
Link
Diversity Only—Specifies that only fiber-diverse primary and alternate paths
for path protection portions of the complete circuit path are needed. The paths
might be node-diverse, but CTC does not check for node diversity.
Click
Next.
Step 11
In the TP
Tunnel Circuit Routing Constraints screen of the wizard, the route of the
MPLS–TP tunnel is displayed.
In the
route, choose the nodes appropriately to include or exclude in the MPLS–TP
tunnel.
Click
Next.
Step 12
In the TP
Tunnel Circuit Label Preview screen of the wizard:
Change the
local label and outgoing label for working LSP and protect LSP as appropriate.
Click
Apply.
Click
Finish
to create an MPLS–TP tunnel.
It is not
recommended to delete the MPLS–TP tunnel in Partial state. For example, the
tunnel is in Partial state due to missing intermediate LSP information. If you
delete this Partial tunnel, you cannot delete the LSP information on the
intermediate node and reuse the tunnel bandwidth.
When you
change the PPC paths of a tunnel in Discovered state, you cannot delete the LSP
information on the intermediate node. For example, consider a tunnel that spans
three nodes A, B, and C. The PPC links from A to B and B to C are deleted and a
direct PPC link is created from A to C. In this case, the LSP information on
the intermediate node B cannot be deleted.
Step 13
Return to your
originating procedure (NTP).
