OSPF单区域配置几个实验

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。 验证 R1     20.0.0.0/30 is subnetted, 1 subnets C       20.0.0.0 is directly connected, FastEthernet0/0      10.0.0.0/30 is subnetted, 1 subnets C       10.0.0.0 is directly connected, FastEthernet1/0      192.168.1.0/32 is subnetted, 1 subnets O       192.168.1.1 [110/2] via 10.0.0.1, 00:00:03, FastEthernet1/0      192.168.2.0/32 is subnetted, 1 subnets C       192.168.2.1 is directly connected, Loopback0      192.168.3.0/32 is subnetted, 1 subnets O       192.168.3.1 [110/2] via 20.0.0.2, 00:00:03, FastEthernet0/0 R2      20.0.0.0/30 is subnetted, 1 subnets O       20.0.0.0 [110/2] via 10.0.0.2, 00:00:31, FastEthernet0/0      10.0.0.0/30 is subnetted, 1 subnets C       10.0.0.0 is directly connected, FastEthernet0/0      192.168.1.0/32 is subnetted, 1 subnets C       192.168.1.1 is directly connected, Loopback0      192.168.3.0/32 is subnetted, 1 subnets O       192.168.3.1 [110/3] via 10.0.0.2, 00:00:31, FastEthernet0/0 R3      20.0.0.0/30 is subnetted, 1 subnets C       20.0.0.0 is directly connected, FastEthernet0/0      10.0.0.0/30 is subnetted, 1 subnets O       10.0.0.0 [110/2] via 20.0.0.1, 00:01:00, FastEthernet0/0      192.168.1.0/32 is subnetted, 1 subnets O       192.168.1.1 [110/3] via 20.0.0.1, 00:01:00, FastEthernet0/0      192.168.3.0/32 is subnetted, 1 subnets C       192.168.3.1 is directly connected, Loopback0   实验2 lo 0 做Router ID  lo 1 模拟路由器下所带计算机
