How to configure EIGRP

EIGRP can be configured for IP, IPv6, IPX and AppleTalk. There are two modes from which EIGRP command are entered: router configuration mode and interface configuration mode. Router configuration mode enables the protocol, determines which networks will run EIGRP, and sets global characteristics. Interface configuration mode allows customization of summaries, metrics, timers and bandwidth.

To start an EIGRP session on a router, use the router eigrp command followed by the autonomous system number of your network. You then enter the network numbers connected to the router using the network command followed by the network number. Example below:

Router#config t

Router(config)#router eigrp 90

Router(config-router)#network 192.168.10.0

Router(config-router)#network 172.16.0.0.

NOTE: Understand that the AS number is irrelevant – that is, as long as all routers use the same number! You can use any number from 1 to 65,535.
