The EIGRP Configuration To display the EIGRP configuration information, perform one of the following tasks: Command Purpose show {ip | ipv6} eigrp [instance-tag] Displays a summary of the configured EIGRP processes. show {ip | ipv6} eigrp [instance-tag] interfaces [type number] [brief] [detail] Displays information about all configured EIGRP interfaces. show {ip | ipv6} eigrp instance-tag neighbors [type number] [detail] Displays information about all the EIGRP neighbors. Use this command to verify the EIGRP neighbor configuration. show {ip | ipv6} eigrp [instance-tag] route [ip-prefix/length] [active] [all-links] [detail-links] [pending] [summary] [zero-successors] [vrf vrf-name] Displays information about all the EIGRP routes. show {ip | ipv6} eigrp [instance-tag] topology [ip-prefix/length] [active] [all-links] [detail-links] [pending] [summary] [zero-successors] [vrf vrf-name] Displays information about the EIGRP topology table. show running-configuration eigrp Displays the current running EIGRP configuration. Monitoring EIGRP To display EIGRP statistics, use the following commands: Command Purpose show {ip | ipv6} eigrp [instance-tag] accounting [vrf vrf-name] Displays accounting statistics for EIGRP. show {ip | ipv6} eigrp [instance-tag] route-map statistics redistribute Displays redistribution statistics for EIGRP. show {ip | ipv6} eigrp [instance-tag] traffic [vrf vrf-name] Displays traffic statistics for EIGRP. Configuration Examples for EIGRP This example shows how to configure EIGRP: feature eigrpinterface ethernet 1/2 ip address 192.0.2.55/24 ip router eigrp Test1 no shutdownrouter eigrp Test1 router-id 192.0.2.1 The following example shows how to use a route map with the distribute-list command to filter routes that are dynamically received from (or advertised to) EIGRP peers. The example configures a route map to match an EIGRP external protocol metric route with an allowable deviation of 100, a source protocol of BGP, and an autonomous system number of 45000. When the two match clauses are true, the tag value of the destination routing protocol is set to 5. The route map is used to distribute incoming packets for an EIGRP process. switch(config)# route-map metric-rangeswitch(config-route-map)# match metric external 500 +- 100switch(config-route-map)# set tag 5switch(config-route-map)# exitswitch(config)# router eigrp 1switch(config-router)# exitswitch(config)# interface ethernet 1/2switch(config-if)# ip address 172.16.0.0switch(config-if)# ip router eigrp 1switch(config-if)# ip distribute-list eigrp 1 route-map metric-range in The following example shows how to use a route map with the redistribute command to allow routes that are redistributed from the routing table to be filtered with a route map before being admitted into an EIGRP topology table. The example shows how to configure a route map to match EIGRP routes with a metric of 110, 200, or an inclusive range of 700 to 800. When the match clause is true, the tag value of the destination routing protocol is set to 10. The route map is used to redistribute EIGRP packets. switch(config)# route-map metric-eigrpswitch(config-route-map)# match metric 110 200 750 +- 50switch(config-route-map)# set tag 10switch(config-route-map)# exitswitch(config)# router eigrp 1switch(config-router)# redistribute eigrp route-map metric-eigrpswitch(config-router)# exitswitch(config)# interface ethernet 1/2switch(config-if)# ip address 172.16.0.0switch(config-if)# ip router eigrp 1 Related Topics See Configuring Route Policy Manager, for more information on route maps.
