PC2:ip 172.16.3.2 255.255.255.0
接下来是本章节重点! 配置OSPF
Switch 1
Switch(config)#router ospf 1 (开启OSPF协议 进程号为1)
Switch(config-router)#network 172.16.5.0 255.255.255.0 area 0 (宣告自己的直连网络,并分配区域号)
Switch(config-router)#network 172.16.1.0 255.255.255.0 area 0 (宣告自己的直连网络,并分配区域号)
Router1
Router(config)#router ospf 1
Router(config-router)#network 172.16.1.0 255.255.255.0 area 0
Router(config-router)#network 172.16.2.0 255.255.255.0 area 0
Router2
Router(config)#router ospf 1
Router(config-router)#network 172.16.1.0 255.255.255.0 area 0
Router(config-router)#network 172.16.2.0 255.255.255.0 area 0
此时 全网互联互通
