一·实验目的

通过本实验，可掌握一下技能：

*会在路由器上启动ospf协议

*能让相应网络进入OSPF进程

*查看OSPF路由信息

*查看OSPF协议信息 

二·实验拓扑图及接口IP地址

三、实验配置步骤

Router0(config)#interface loopback 0

 Router0(config-if)#ip address 1.1.1.1 255.255.255.0 

Router0(config-if)#no shutdown 

Router0(config-if)# Router1(config)#interface loopback 0

 Router1(config-if)#ip address 2.2.2.2 255.255.255.0 

Router1(config-if)#no shutdown

Router2(config)#interface loopback 0 

 Router2(config-if)#ip address 3.3.3.3 255.255.255.0

 Router2(config-if)#no shutdown

分别去除EIGRP然后配置OSPF

Router0(config)#no route eig 100 

Router0(config)#router ospf 100 

 Router0(config-router)#network 192.168.0.0 0.0.255.255 area 0

 Router0(config-router)# Router1(config)#no router eig 100 

Router1(config)#router ospf 100

 Router1(config-router)#network 192.168.0.0 0.0.255.255 area 0

 Router1(config-router)# Router2(config)#no router eig 100

 Router2(config)#router ospf 100

 Router2(config-router)#network 192.168.0.0 0.0.255.255 area 0

 Router2(config-router)#         #注意：先配置R0 和R2，再配置R1

分别查看R0、R1和R2的路由表
