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：
#

network 192.168.12.0 0.0.0.255

network 192.168.24.0 0.0.0.255
area 0.0.0.3
network 192.168.45.0 0.0.0.255
#
R5：
#
ospf 200 router-id 5.5.5.5

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
