1. Configure the address of each PC
2. Basic router configuration
Add WIC-1T modules to the two routers respectively when they are powered off.
RouterA：
Router>and
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#host
Router(config)#hostname RouterA
RouterA(config)#int f0/0
RouterA(config-if)#ip add 192.168.1.1 255.255.255.0
RouterA(config-if)#no shutdown
RouterA(config)#int s0/3/0
RouterA(config-if)#ip add 192.168.12.1 255.255.255.0
RouterA(config-if)#no shutdown
RouterB：
Router>and
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname RouterB
RouterB(config)#int f0/0
RouterB(config-if)#ip add 192.168.2.1 255.255.255.0
RouterB(config-if)#no shutdown
RouterB(config-if)#exit
RouterB(config)#int s0/3/0
RouterB(config-if)#ip add 192.168.12.2 255.255.255.0
RouterB(config-if)#no shutdown
3. Configure dynamic routing protocol RIP
RouterA：
RouterA(config)#router rip
RouterA(config-router)#net
RouterA(config-router)#network 192.168.1.0
RouterA(config-router)#network 192.168.12.0
RouterA(config-router)#version 2
RouterA(config-router)#end
RouterB：
RouterB(config)#router rip
RouterB(config-router)#net
RouterB(config-router)#network 192.168.2.0
RouterB(config-router)#network 192.168.12.0
RouterB(config-router)#version 2
RouterB(config-router)#end
