Figure 12-1: Network Setup for IP Routing Configuration
- Figure 12-1 shows the network setup for static routing, default routing, RIP, and IGRP
configurations. Note: Both RT2 serial interfaces are DCEs.
- Initial configuration on RT1:
RT1 RT2 RT3
Fa1/0
192.168.1.1
S0/0
192.168.2.1
192.168.2.2
S0/0
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname RT1
RT1(config)#int fa1/0
RT1(config-if)#ip add 192.168.1.1 255.255.255.0
RT1(config-if)#no shut
RT1(config-if)#int s0/0
RT1(config-if)#ip add 192.168.2.1 255.255.255.0
RT1(config-if)#no shut
RT1(config-if)#^Z
RT1#
RT1#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
E1 - OSPF external type 1, E2 - OSPF external type 2, E – EGP
Gateway of last resort is not set
PC1 PC2 PC3 PC4
192.168.1.2 192.168.3.2 192.168.3.3 192.168.5.2
C 192.168.1.0/24 is directly connected, FastEthernet1/0
RT1#
- Route to 192.168.2.0/24 is not shown in the routing table as the line protocol of S0/0 is down.
This happens because the DCE end (RT2) does not provide the clocking yet. The clock rate
interface subcommand defines the timing of data transmission over a synchronous serial link
when back-to-back DTE/DCE serial cables instead of CSU/DSU are being used.
