Chapter 12 Static Routing, Default Routing, RIP, and IGRP Lab 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.

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. 81 Fa1/0 192.168.3.1 S0/1 192.168.4.1 192.168.4.2 S0/0 Fa1/0 192.168.5.1 Copyright © 2008 Yap Chin Hoong yapchinhoong@hotmail.com
