OSPF单区域配置几个实验
 
实验1
 
 
配置路由接口省略
在R1上启动OSPF进程,并配置Router ID 及运行OSPF的接口
R1(config)# router  ospf  1
R1(config-router)# router-id  192.168.2.1
R1(config-router)#network 10.0.0.0  0.0.0.3  area  0
R1(config-router)#network 20.0.0.0  0.0.0.3  area  0
在R2上启动OSPF进程,并配置Router ID 及运行OSPF的接口
R1(config)# router  ospf  1
R1(config-router)# router-id  192.168.1.1
R1(config-router)#network 192.168.1.1  0.0.0.0  area  0
R1(config-router)#network 10.0.0.0  0.0.0.3  area  0
在R3上启动OSPF进程,并配置Router ID 及运行OSPF的接口
R1(config)# router  ospf  1
R1(config-router)# router-id  192.168.3.1
R1(config-router)#network 192.168.3.1  0.0.0.0  area  0
R1(config-router)#network 20.0.0.0  0.0.0.3  area  0
  在R1上,没有将loopback  192.168.2.1宣告进ospf网络中,而在R2的配置中将loopback 192.168.1.1宣告进了ospf网络中,因此,loopback接口是否需要启用ospf,可以视需求而定,不过无论loopback接口是否启用ospf,loopback接口的IP地址都可以成为Router ID。
