The IP Routing Process 243
Router (config)#hostname 2621A
2621A(Config)#interface fa0/0
2621A(Config-if)#ip address 172.16.10.1 255.255.255.0
2621A(Config-if)#no shut
The configuration is only a few lines. If you have a hard time understanding
this process, refer to Chapter 4.
To view the IP routing tables created on a Cisco router, use the privileged
mode command show ip route. The command output is shown as follows.
Notice that only the configured network is shown in the routing table. This
means the router only knows how to get to network 172.16.10.0.
2621A#sh ip route
Codes: C - connected, S - static, I - IGRP, 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, E – EGP i - IS-IS, L1 - IS-IS level-
1, L2 - IS-IS level-2, * - candidate default U - per-user
static route, o - ODR, P - periodic downloaded static
route T - traffic engineered route
Gateway of last resort is not set
172.16.0.0/24 is subnetted, 1 subnets
C 172.16.10.0 is directly connected, FastEthernet0/0
2621A#
The preceding routing table shows the directly connected network
172.16.10.0. Notice the “C”; this means that the network is directly connected.
The codes for each type of connection are listed at the top of the show
ip route command with their abbreviations. In the interest of brevity, the
codes will be abbreviated in the rest of this chapter.
2501A Configuration
It is now time to configure the next router. To configure 2501A, two interfaces
need to be configured: Ethernet 0 and serial 0.
