接下來是本章節重點！ 配置OSPF
Switch 1
Switch(config)#router ospf 1 （開啓OSPF協議 進程號爲1）
Switch(config-router)#network 172.16.5.0 255.255.255.0 area 0 （宣告自己的直連網絡，並分配區域號）
Switch(config-router)#network 172.16.1.0 255.255.255.0 area 0 （宣告自己的直連網絡，並分配區域號）
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
此時 全網互聯互通
