交换机配置OSPF：设备名称与拓扑图一样，路由表中设备名称与拓扑图名称不一致，但是同一设备

SW3-2:

ospf 1

 area 0.0.0.0

  network 192.168.10.0 0.0.0.255

  network 192.168.20.0 0.0.0.255

  network 192.168.12.0 0.0.0.3

SW3-1-1:

ospf 1

 area 0.0.0.0

  network 192.168.13.0 0.0.0.3

  network 192.168.30.0 0.0.0.255

  network 192.168.40.0 0.0.0.255

  network 192.168.50.0 0.0.0.255

SW4-1:

ospf 1

 area 0.0.0.0

  network 192.168.12.0 0.0.0.3

  network 192.168.13.0 0.0.0.3

都配置完成后，ping一下

可以看到，实现了全网互通

实验结束
