Command

Purpose

 

 

 

Step 1

router eigrp as-number

Enters router configuration mode, and enables

 

 

EIGRP on the router. The autonomous-system

 

Example:

number identifies the route to other EIGRP routers

 

Router(config)# router eigrp 109

and is used to tag the EIGRP information.

 

Router(config)#

 

 

 

 

Step 2

network ip-address

Specifies a list of networks on which EIGRP is to

 

 

be applied, using the IP address of the network of

 

Example:

directly connected networks.

 

Router(config)# network 192.145.1.0

 

 

Router(config)# network 10.10.12.115

 

 

Router(config)#

 

 

 

 

Step 3

end

Exits router configuration mode, and enters

 

Example:

privileged EXEC mode.

 

 

 

Router(config-router)# end

 

 

Router#

 

 

 

 

Example

The following configuration example shows the EIGRP routing protocol enabled in IP networks 192.145.1.0 and 10.10.12.115. The EIGRP autonomous system number is 109.

To see this configuration, use the show running-configcommand, beginning in privileged EXEC mode.

Verifying Configuration

To verify that you have properly configured IP EIGRP, enter the show ip route command, and look for EIGRP routes indicated by “D.” You should see verification output similar to the following:

 

 

 

Router# show ip route

 

 

 

 

 

 

Codes: C - connected,

S - static, R - RIP, M - mobile, B - BGP

 

 

 

D - EIGRP, EX - EIGRP external,

O - OSPF, IA - OSPF inter area

 

 

 

N1

- OSPF NSSA

external type 1,

N2 - OSPF NSSA external type 2

 

 

 

E1

- OSPF external type 1, E2 -

OSPF external type 2
