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(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 static routing
RouterA(config)#ip route 192.168.2.0 255.255.255.0 192.168.12.2
RouterA#show ip route
RouterB(config-if)#ip route 192.168.1.0 255.255.255.0 192.168.12.1
RouterB#show ip route
