实验八OSPF的基本配置OSPF路由协议
基本的OSPF配置
对于基本的OSPF配置，需要进行的操作包括：
●配置Router ID
●启动OSPF
●进入OSPF区域视图
●在指定网段使能OSPF
OSPF的基本配置
【需求】
两台PC所在网段，通过两台使用OSPF协议的路由器实现互连互通。【组网图】
S1/0 S1/0
【验证】
RouterA和RouterB可以通过OSPF学习到对方路由信息，并可以ping通对方网段。RouterA路由表：
[RouterA] dis ip rout
Routing Table: public net
Destination/Mask Protocol Pre Cost Nexthop Interface 1.1.1.1/32 DIRECT 0 0 127.0.0.1 InLoopBack0
1.1.1.2/32 OSPF 10 1563 20.1.1.2 Serial0/0 10.1.1.0/24 DIRECT 0 0 10.1.1.1 Ethernet0/0

20.1.1.0/30 DIRECT 0 0 20.1.1.1 Serial0/0 20.1.1.1/32 DIRECT 0 0 127.0.0.1 InLoopBack0

127.0.0.1/32 DIRECT 0 0 127.0.0.1 InLoopB
Ping 30.1.1.2
验证是否PC1能PING 通 PC2 ？
RouterB路由表：
