set metric (EIGRP)
To set the metric value for Enhanced Interior Gateway Routing Protocol (EIGRP) in a route map, use the set metric route-map configuration command. To return to the default metric value, use the no form of this command.
set metric bandwidth delay reliability loading mtu
no set metric bandwidth delay reliability loading mtu
Syntax Description
Defaults
No metric will be set in the route map.
Command Modes
Route-map configuration (config-route-map)
Command History
Usage Guidelines
We recommend you consult your Cisco technical support representative before changing the default value.
Use the route-map global configuration command, and the match and set route-map configuration commands, to define the conditions for redistributing routes from one routing protocol into another. Each route-map command has a list of match and set commands associated with it. The match commands specify the match criteria—the conditions under which redistribution is allowed for the current route-map command. The set commands specify the set actions—the particular redistribution actions to perform if the criteria enforced by the match commands are met. The no route-map command deletes the route map.
The set route-map configuration commands specify the redistribution set actions to be performed when all of the match criteria for a router are met. When all match criteria are met, all set actions are performed.
Examples
The following example sets the bandwidth to 10,000, the delay to 10, the reliability to 255, the loading to 1, and the MTU to 1500:
Router(config-route-map)# set metric 10000 10 255 1 1500show eigrp address-family accounting

stub
Note
To configure a router as a stub using Enhanced Interior Gateway Routing Protocol (EIGRP), use the stub command in router configuration mode. To disable the EIGRP stub routing feature, use the no form of this command.
stub [receive-only | connected | static | summary | redistributed]
no stub [receive-only | connected | static | summary | redistributed]
Syntax Description
Command Default
Stub routing is not enabled.
Command Modes
Router configuration (config-router)
Command History
Usage Guidelines
Use the stub command to configure a router as a stub where the router directs all IPv6 traffic to a distribution router.
The stub command can be modified with keywords, and more than one keyword can be used in the same syntax. These options can be used in any combination, except for the receive-only keyword. The receive-only keyword will restrict the router from sharing any of its routes with any other router in that EIGRP autonomous system, and the receive-only keyword will not permit any other option to be specified because it prevents any type of route from being sent. The connected, static, summary, and redistributed keywords can be used in any combination but cannot be used with the receive-only keyword.
If any of these four keywords is used with the stub command, only the route types specified by the particular keywords will be sent. Route types specified by the nonused keywords will not be sent.
The connected keyword permits the EIGRP stub routing feature to send connected routes. If the connected routes are not covered by a network statement, it may be necessary to redistribute connected routes with the redistribute connected command under the EIGRP process. This option is enabled by default.
The static keyword permits the EIGRP stub routing feature to send static routes. Without the configuration of this option, EIGRP will not send any static routes, including internal static routes that normally would be automatically redistributed. It will still be necessary to redistribute static routes with the redistribute static command.
The summary keyword permits the EIGRP stub routing feature to send summary routes. Summary routes can be created manually with the ipv6 summary address eigrp command or automatically at a major network border router with the auto-summary command enabled. This option is enabled by default.
The redistributed keyword permits the EIGRP stub routing feature to send other routing protocols and autonomous systems. Without the configuration of this option, EIGRP will not advertise redistributed routes.
Note
Examples
In the following example, the stub command is used to configure the router as a stub that advertises connected and summary routes:
ipv6 router eigrp 1network 3FEE:12E1:2AC1:EA32::/64stubIn the following example, the stub command is issued with the connected and static keywords to configure the router as a stub that advertises connected and static routes (sending summary routes will not be permitted):

summary-address (EIGRP)
To configure a summary address for Enhanced Interior Gateway Routing Protocol (EIGRP), use the summary-address (EIGRP) command in address-family interface configuration mode. To remove an EIGRP summary address, use the no form of this command.
summary-address ip-address mask [administrative-distance [leak-map leak-map-name]]
no summary-address ip-address mask [administrative-distance [leak-map leak-map-name]]
Syntax Description
Command Default
All routes are advertised individually.
Command Modes
Address-family interface configuration (config-router-af-interface)
Command History
Usage Guidelines
The summary-address (EIGRP) command is used to configure interface-level address summarization. EIGRP summary routes are given an administrative distance value of 5. The administrative distance metric is used to advertise a summary address without installing it in the routing table.
By default, EIGRP summarizes subnet routes to the network level. The no auto-summary command can be entered to configure subnet-level summarization.
EIGRP Support for Leaking Routes
Configuring the leak-map keyword allows you to advertise a component route that would otherwise be suppressed by the manual summary. Any component subset of the summary routes or addresses can be leaked. A route map and access list must be defined to source the leaked route.
The following is default behavior if an incomplete configuration is entered:
•
•
Examples
The following example shows how to configure an EIGRP summary address:
Router(config)# router eigrp virtual-nameRouter(config-router)# address-family ipv4 autonomous-system 4453Router(config-router-af)# af-interface ethernet0/0Router(config-router-af-interface)# summary-address 192.168.0.0 255.255.0.0 95Related Commands
summary-metric
To configure a fixed metric for an Enhanced Interior Gateway Routing Protocol (EIGRP) summary aggregate address, use the summary-metric command in address-family topology configuration mode. To remove a configured metric, use the no form of this command.
summary-metric network-address subnet-mask [bandwidth delay reliability load mtu] [distance administrative-distance]
no summary-metric network-address subnet-mask
Syntax Description
Command Default
EIGRP summary aggregate addresses do not have a fixed metric.
Command Modes
Address-family topology configuration (config-router-af-topology)
Command History
Usage Guidelines
When EIGRP creates a summary route, it includes a metric with the route in order to advertise it.
EIGRP searches for components of the summary to be suppressed and represented by the summary. EIGRP finds the component with the best metric and copies the metric from it into the summary. Components of the summary may come and go, which means that every time the best component changes, the summary needs to be re-advertised to all of its peers. Even if the best component is not the one that changed, EIGRP still has to search every topology entry to make sure the summary is not affected. This can add significant processing overhead.
Use the summary-metric command to mitigate this metric churn and processing overhead. Rather than searching for the best component metric, EIGRP uses the values configured with the summary-metric command.
Changes Beginning in Cisco IOS XE 3.2S
One of the sets of optional values is required after the subnet mask. That is, you can configure bandwidth, delay, reliability, load, and MTU, along with administrative distance, without administrative distance, or you can configure only administrative distance.
The preferred way to configure administrative distance for summaries is by using the summary-metric command; the administrative distance option in the summary-address command is being deprecated.
If the summary-address with administrative distance is entered, and:
•
•
Examples
The following example configures an EIGRP summary address and sets the bandwidth to 10,000, the delay to 10, the reliability to 255, the load to 1, and the MTU to 1500 for the summary address 192.168.0.0/16:

timers graceful-restart purge-time
To set the route-hold timer to determine how long a nonstop forwarding (NSF)-aware router that is running Enhanced Interior Gateway Routing Protocol (EIGRP) will hold routes for an inactive peer, use the timers graceful-restart purge-time command in router configuration, address-family, or service-family configuration mode. To return the route-hold timer to the default value, use the no form of this command.
timers graceful-restart purge-time seconds
no timers graceful-restart purge-time
Syntax Description
seconds
Time, in seconds, for which EIGRP will hold routes for an inactive peer. The configurable time range is from 20 to 300 seconds. The default is 240 seconds.
Command Default
EIGRP NSF awareness is enabled by default. The default value for the route-hold timer is 240 seconds.
Command Modes
Router configuration (config-router)
Address-family configuration (config-router-af)
Service-family configuration (config-router-sf)Command History
Usage Guidelines
The route-hold timer sets the maximum period of time for which the NSF-aware router will hold known routes for an NSF-capable neighbor during a switchover operation or a well-known failure condition. The route-hold timer is configurable so that you can tune network performance and avoid undesired effects, such as "black holing" routes if the switchover operation takes too much time. When this timer expires, the NSF-aware router scans the topology table and discards any stale routes, allowing EIGRP peers to find alternate routes instead of waiting during a long switchover operation.
Examples
The following configuration example sets the route-hold timer value for an NSF-aware address family. In the example, the route-hold timer is set to 1 minute:
Router(config)# router eigrp virtual-nameRouter(config-router)# address-family ipv4 autonomous-system 1Router(config-router-af)# timers graceful-restart purge-time 60The following configuration example sets the route-hold timer value for an NSF-aware service-family.

topology (EIGRP)
To configure an Enhanced Interior Gateway Routing Protocol (EIGRP) process to route IP traffic under the specified topology instance and to enter address-family topology configuration mode, use the topology command in address-family configuration mode. To disassociate the EIGRP routing process from the topology instance, use the no form of this command.
topology {base | topology-name tid number}
no topology topology-name
Syntax Description
Command Default
EIGRP routing processes are not configured to route IP traffic under a topology instance.
Command Modes
Address-family configuration (config-router-af)
Command History
Usage Guidelines
The topology command is used in a Multi-Topology Routing (MTR) configuration to enable an EIGRP process under the specified topology. The topology command is entered under address-family configuration mode. Command configurations are applied only to the topology instance. The topology must be defined globally with the global-address-family command in global address-family configuration mode before the topology can be configured under the EIGRP process.
The tid keyword associates an ID with the topology instance. Each topology must be configured with a unique topology ID. The topology ID is used to identify and group Network Layer Reachability Information (NLRI) for each topology in EIGRP updates.
The topology ID must be consistent across routers so that EIGRP can correctly associate topologies.
Examples
The following example configures EIGRP process 1 to route traffic for the 192.168.0.0/16 network under the VOICE topology instance:
Router(config)# router eigrp 1Router(config-router)# address-family ipv4 unicast autonomous-system 3Router(config-router-af)# topology VOICE tid 100Router(config-router-af-topology)# no auto-summaryRouter(config-router-af-topology)# network 192.168.0.0 0.0.255.255Router(config-router-af-topology)# endRelated Commands
traffic-share balanced
To control how traffic is distributed among routes when multiple routes for the same destination network have different costs, use the traffic-share balanced command in router configuration mode or address-family topology configuration mode. To disable this function, use the no form of the command.

no traffic-share balanced
Syntax Description
This command has no arguments or keywords.
Command Default
Traffic is distributed proportionately to the ratios of the metrics.
Command Modes
Router configuration (config-router)
Address-family topology configuration (config-router-af-topology)Command History
Usage Guidelines
This command applies only to Enhanced Interior Gateway Routing Protocol (EIGRP). With the default setting, routes that have higher metrics represent less-preferable routes and get less traffic.
Examples
In the following example, traffic is balanced across multiple routes:
Router(config)# router eigrp 5Router(config-router)# traffic-share balancedRouter(config-router)# variance 1In the following EIGRP named configuration example, traffic is balanced across multiple routes:

variance (EIGRP)
To control load balancing in an internetwork based on the Enhanced Interior Gateway Routing Protocol (EIGRP), use the variance command in router configuration mode or address-family topology configuration mode. To reset the variance to the default value, use the no form of this command.
variance multiplier
no variance
Syntax Description
multiplier
Metric value used for load balancing. It can be a value from 1 to 128. The default is 1, which means equal-cost load balancing.
Command Default
EIGRP uses equal-cost load balancing.
Command Modes
Router configuration (config-router)
Address-family topology configuration (config-router-af-topology)Command History
Usage Guidelines
Setting a variance value enables EIGRP to install multiple loop-free routes with unequal cost in a local routing table. A route learned through EIGRP must meet two criteria to be installed in the local routing table:
•
•
Thus, if the variance is set to 1, only routes with the same metric as the successor are installed in the local routing table. If the variance is set to 2, any EIGRP-learned route with a metric less than 2 times the successor metric will be installed in the local routing table.
Note
Examples
The following example sets a variance value of 4:
Router(config)# router eigrp 109Router(config-router)# variance 4The following example sets a variance value of 4 in address-family topology configuration mode:
Router(config)# router eigrp virtual-nameRouter(config-router)# address-family ipv4 autonomous-system 4453Router(config-router-af)# network 10.0.0.0Router(config-router-af)# topology baseRouter(config-router-af-topology)# variance 4
