2501B
2501C
IP Routing in Our Network 251
The 2501A router now has a complete routing table. As long as the other
routers in the internetwork have the same routing table, 2501A can communicate
to all remote networks.
The 2501B router is directly connected to networks 172.16.20.0,
172.16.30.0, and 172.16.40.0. Only two routers need to be added:
172.16.10.0 and 172.16.50.0.
2501B(Config)#ip route 172.16.10.0 255.255.255.0
172.16.20.1
2501B(Config)#ip route 172.16.50.0 255.255.255.0
172.16.40.2
The following output shows the routing table on the 2501B router.
2501B#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, 5 subnets
S 172.16.50.0 [1/0] via 172.16.40.2
C 172.16.40.0 is directly connected, Serial1
C 172.16.30.0 is directly connected, Ethernet0
C 172.16.20.0 is directly connected, Serial0
S 172.16.10.0 [1/0] via 172.16.20.1

2501B now shows all the networks in the internetwork and can communicate
to all routers and networks, with the exception of the hosts on network
172.16.50.0; this is because 2501C is not configured yet.
Router 2501C is directly connected to networks 172.16.40.0 and
172.16.50.0. The routing table needs to know about networks 172.16.10.0,
172.16.20.0, and 172.16.30.0. Here is the configuration:
2501C(Config)#ip route 172.16.10.0 255.255.255.0
172.16.40.1
