EIGRP Commands

Enabling EIGRP Routing

Router(config)# router eigrp AS number (Must be the same on all routers)

Router(config-router)# network network-address [wildcard mask]

EIGRP Interface commands

Router(config-if)# ip summary-address eigrp as-number network-address mask

• RTC(config-if)#ip summary-address eigrp 2446 2.1.0.0 255.255.0.0

Router(config-if)# no auto-summary

• auto-summary on by default. EIGRP summarizes automatically between classful boundaries. Must be used for VLSM.

Router(config-if)#bandwidth kilobits

• Configures the bandwidth used by routing metrics on the outgoing interface.

Router(config-if)#ip bandwidth-percent eigrp as-number bandwidth-percentage

• By default, EIGRP is set to use only up to 50% of the bandwidth of an interface to exchange routing information.

Router(config-router)#eigrp log-neighbor-changes

• This command enables the logging of neighbor adjacency changes to monitor the stability of the routing system and to help detect problems.

RTA(config-router)# variance number

• The variance command instructs the router to include routes with a metric less than or equal to n times the minimum metric route for that destination, where n is the number specified by the variance command.

Miscellaneous

Router(config-router)# default-metric 56 100 255 10 1500 {k values)

Show commands

Router# show ip eigrp neighbors {displays neighbors}

Router# show ip eigrp topology

Router# show ip eigrp topology all links

• displays topology, active/passive (well) state, successors

Router# debug eigrp fsm

Router# debug eigrp packet

Router# show ip route eigrp {EIGRP routes in routing table}

Router# show ip protocols

• AS number, filtering, redistribution, neighbors, distance

Router# show ip eigrp traffic EIGRP packets sent and received

Redistribution

Example 1 : EIGRP and IGRP redistributes automatically as long as the same process-id is used.

Router(config)# router eigrp 44 and Router(config)# router igrp 44
