2501A(config)#int e0
2501A(config-if)#ip address 172.16.10.2 255.255.255.0
2501A(config-if)#no shut
2501A(config-if)#int s0
2501A(config-if)#ip address 172.16.20.1 255.255.255.0
2501A(config-if)#no shut
The preceding configuration configured serial 0 into network
172.16.20.0 and Ethernet 0 into network 172.16.10.0. The show ip route
command displays the following:
2501A#sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP,
M – [output cut]
Gateway of last resort is not set
172.16.0.0/24 is subnetted, 2 subnets
C 172.16.20.0 is directly connected, Serial0
C 172.16.10.0 is directly connected, Ethernet0
2501A#
Notice that router 2501A knows how to get to networks 172.16.10.0 and
172.16.20.0. Router 2621 and Router A can communicate because they are
on the same LAN.
2501B Configuration
The configuration of 2501B is more of the same, except that you also need
to add the clock rate command to the DCE interfaces connected to both
serial interfaces. For more information on the DCE interfaces and the clock
rate command, please see Chapter 4.
