我们将以上面的拓扑图进行本次ospf的实验，目的是能当三台pc机互通
先配置好pc机的IP地址，注意一定要给pc机设置好网关，接下来配置路由器的IP地址
router4
enable 进入特权模式
config t 进入全局配置模式
interface g0/0
ip address 192.168.1.254 255.255.255.0
no shu
exit
interface s0/3/0
ip address 192.168.10.1 255.255.255.0
no shu
router1
enable
config t
interface s0/3/0
ip address 192.168.10.2 255.255.255.0
clock rate 6400 同步时间
no shu
exit
interface s0/3/1
ip address 192.168.20.1 255.255.255.0
clock rate 6400

exit
interface s0/2/0
ip address 192.168.40.1 255.255.255.0

路由器的IP地址配置完毕
配置ospf
router4
在全局配置模式下
router ospf 1
router-id 1.1.1.1
network 192.168.1.0 0.0.0.255 area 0
network 192.168.10.0 0.0.0.255 area 0
router1
在全局配置模式下
router ospf 1
router-id 2.2.2.2
network 192.168.10.0 0.0.0.255 area 0
network 192.168.20.0 0.0.0.255 area 0
network 192.168.40.0 0.0.0.255 area 0

在全局配置模式下
router ospf 1
router-id 4.4.4.4
network 192.168.40.0 0.0.0.255 area 0
network 192.168.50.0 0.0.0.255 area 0

router3
在全局配置模式下
router ospf 1
router-id 5.5.5.5
network 192.168.3.0 0.0.0.255 area 0
network 192.168.30.0 0.0.0.255 area 0
router5
在全局配置模式下
router ospf 1
router-id 6.6.6.6
network 192.168.2.0 0.0.0.255 area 0

ospf全部配置完毕，等待路由器之间相互学习，可以在特权模式下使用show ip route来查看路由表的学习情况
学习完毕可以使用ping命令，三台pc机就可以互通了，到此实验完成
