7.1单区域OSPF配置 7.1.1单区域OSPF配置 单区域OSPF的配置分为两个步骤 >启动OSPF路由器协议进程 Router(config)router ospf Process-ID >声明运行OSPF协议的路由器接口IP地址或子网地址 o Router(config-router)#network A.B.C. D A.B.C.D area area-id
7.1 单区域OSPF配置 7.1.1 单区域OSPF配置 单区域OSPF的配置分为两个步骤： 启动OSPF路由器协议进程。 Router(config)#router ospf Process-ID 声明运行OSPF协议的路由器接口IP地址或子网地址。 Router(config-router)#network A.B.C.D A.B.C.D area area-id
