EIGRP Command List

EIGRP Command List

You configure EIGRP just the same as you would configure IGRP. The following table lists the applicable commands.

Command	Function
Router(config)#router eigrp number	Defines an EIGRP process. The number must match between routers for information to be shared.
Router(config-router)#network n.n.n.n Router(config-router)#network n.n.n.n w.w.w.w	Identifies a network that participates in the routing process. Networks can be specified with or without the wildcard mask. If you do not use a wildcard mask, the network address you add will be automatically truncated based on classful network boundaries. You must use a wildcard mask to identify VLSM subnets.
Router(config-router)#no auto-summary	Turn off automatic route summarization. With automatic route summarization, subnets are summarized based on classful boundaries when advertising routes on networks with a different class boundary. You must disable automatic summarization if you have a network address (such as 10.0.0.0) subnetted into smaller subnets and separated by a network with a different classful network address (such as 12.0.0.0).

Example
The following commands enable EIGRP on a router and define three networks that participate in the routing process.

Router(config)#router eigrp 2
Router(config-network)#network 172.16.1.0 0.0.0.255
Router(config-network)#network 172.16.2.0 0.0.0.255
Router(config-network)#network 172.16.3.0 0.0.0.255

Use the following commands to manage and monitor EIGRP.

Command	Features
show ip route	View EIGRP-learned routes.
show eigrp neighbors	View neighboring routers from which EIGRP routes can be learned. Lists the IP address of the connected router.
show eigrp interfaces	View the interfaces that are running EIGRP and the number of connected routers.
