拓扑：
配置思路：
1、配置接口地址：
R1：G0/0/0：192.168.12.1/24 lo0:110.40.6.1/24
R2：G0/0/0：192.168.12.2/24 G0/0/1:192.168.24.2/24 G0/0/2:192.168.23.2/24
R3：G0/0/3：192.168.23.3/24 lo0:10.157.120.1/24
R4：G0/0/0：192.168.45.4/24 G0/0/1:192.168.24.4/24
R5：G0/0/0：192.168.45.5/24 lo0:172.40.1.1/24
2、配置ospf协议
R1：
#
ospf 200 router-id 1.1.1.1
area 0.0.0.1
network 192.168.12.0 0.0.0.255
network 110.40.6.0 0.0.0.255
#
R2：

network 192.168.45.0 0.0.0.255
#
R5：
#
ospf 200 router-id 5.5.5.5
area 0.0.0.3
network 192.168.45.0 0.0.0.255
network 172.40.1.0 0.0.0.255
#
3、测试网络
1）在R1上测试R5的回环口
PING 172.40.1.1: 56 data bytes, press CTRL_C to break

round-trip min/avg/max = 70/148/400 ms
2）在R1上测试R3的回环口

round-trip min/avg/max = 30/76/160 ms
3）在R3上测试R5的回环口
PING 172.40.1.1: 56 data bytes, press CTRL_C to break
Reply from 172.40.1.1: bytes=56 Sequence=1 ttl=253 time=80 ms
