 cisco怎样配置OSPF虚链路,小编带来了cisco配置OSPF虚链路的方法，供大家学习。 这个配置将验证一个OSPF虚电路(Virtual-Link)的过程，重点在观察虚链路连接的临时网络与正常区域间路由有何区别。上图中区域4(area 4)没有和area 0直接相连。在R2与R3之间配置了一条虚链路。 // R1 // int lo0 ip ad 1.1.1.1 255.255.255.0 int e0 ip ad 192.1.1.1 255.255.255.0 router os 1 network 192.1.1.0 0.0.0.255 area 0 // R2 // int lo0 ip ad 2.2.2.2 255.255.255.0 int e0 ip ad 192.1.1.2 255.255.255.0 int e1 ip ad 193.1.1.2 255.255.255.0 router os 1 network 192.1.1.0 0.0.0.255 area 0 network 193.1.1.0 0.0.0.255 area 1 // R3 // int lo0 ip ad 3.3.3.3 255.255.255.0 int e1 ip ad 193.1.1.3 255.255.255.0 int e0 ip ad 194.1.1.3 255.255.255.0 router os 1 network 193.1.1.0 0.0.0.255 area 1 network 194.1.1.0 0.0.0.255 area 4 // R4 // int lo0 ip ad 4.4.4.4 255.255.255.0 int e0 ip ad 194.1.1.4 255.255.255.0 router os 1 network 194.1.1.0 0.0.0.255 area 4 基本配置完成后，我们在每台路由器上分别来验证一下： r1#sh ip os nei Neighbor ID Pri State Dead Time Address Interface 2.2.2.2 1 FULL/BDR 00:00:33 192.1.1.2 Ethernet0/0 r1# r1#sh ip ro 1.0.0.0/24 is subnetted, 1 subnets C 1.1.1.0 is directly connected, Loopback0 O IA 193.1.1.0/24 [110/20] via 192.1.1.2, 00:00:19, Ethernet0/0 C 192.1.1.0/24 is directly connected, Ethernet0/0 //注意R1上有关于193.1.1.0的路由条目，是属于IA类型(域间路由) r2#sh ip os nei Neighbor ID Pri State Dead Time Address Interface 1.1.1.1 1 FULL/DR 00:00:35 192.1.1.1 Ethernet0/0 3.3.3.3 1 FULL/BDR 00:00:35 193.1.1.3 Ethernet1/0 r2# r2# r2#sh ip ro 2.0.0.0/24 is subnetted, 1 subnets C 2.2.2.0 is directly connected, Loopback0 C 193.1.1.0/24 is directly connected, Ethernet1/0 C 192.1.1.0/24 is directly connected, Ethernet0/0 r3#sh ip os nei Neighbor ID Pri State Dead Time Address Interface 2.2.2.2 1 FULL/DR 00:00:32 193.1.1.2 Ethernet1/0 4.4.4.4 1 FULL/DR 00:00:34 194.1.1.4 Ethernet0/0 r3#sh ip ro 3.0.0.0/24 is subnetted, 1 subnets C 3.3.3.0 is directly connected, Loopback0 C 193.1.1.0/24 is directly connected, Ethernet1/0 O IA 192.1.1.0/24 [110/20] via 193.1.1.2, 00:02:49, Ethernet1/0 C 194.1.1.0/24 is directly connected, Ethernet0/0 //注意R3中有关于192.1.1.0的路由是属于IA类型(域间路由) |
