Cisco 3900 Series, Cisco 2900 Series, and Cisco 1900 Series Integrated Services Routers Generation 2 Software Configuration Guide
Chapter Basic Router Configuration
Configuring Dynamic Routes
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-config command, beginning in privileged EXEC mode.
Router# show running-config
...
!
router eigrp 109
network 192.145.1.0
network 10.10.12.115

...
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
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
10.0.0.0/24 is subnetted, 1 subnets
C 10.108.1.0 is directly connected, Loopback0
D 3.0.0.0/8 [90/409600] via 2.2.2.1, 00:00:02, Ethernet0/0
