没想到这篇转载的是我们一起学NP班一个同学的，去了他的空间遛了一圈，感触很大~~ 嗯嗯，最后要谢谢songhong同学的总结！！ 拓扑图： 实验需求：R1的LO 0 1.1.1.1/32口重分布到OSPF中 R4的LO 0 4.4.4.4/32口重分布到EIGRP中 1.1.1.1负载均衡从R2 R3到R4 4.4.4.4 负载均衡从R2 R3到R1 实验要点：修改EIGRP 、OSPF管理距离 实验步骤： 基本配置 R1： r1#conf t r1(config)#int f0/0 r1(config-if)#ip add 192.168.12.1 255.255.255.0 r1(config-if)#no sh r1(config-if)#int f1/0 r1(config-if)#ip add 192.168.13.1 255.255.255.0 r1(config-if)#no sh r1(config-if)#int lo 0 r1(config-if)#ip add 1.1.1.1 255.255.255.255 r1(config-if)#^Z r1#conf t r1(config)#router ospf 110 r1(config-router)#router-id 1.1.1.1 r1(config-router)#net 192.168.12.0 0.0.0.255 area 0 r1(config-router)#net 192.168.13.0 0.0.0.255 area 0 r1(config-router)#redistribute connected subnets r1(config-router)#^Z R2： r2#conf t r2(config)#int f0/0 r2(config-if)#ip add 192.168.12.2 255.255.255.0 r2(config-if)#no sh r2(config-if)#int f1/0 r2(config-if)#ip add 192.1.1.2 255.255.255.0 r2(config-if)#no sh r2(config-if)#z ^ r2#conf t r2(config)#router ospf 110 r2(config-router)#router-id 2.2.2.2 r2(config-router)#net 192.168.12.0 0.0.0.255 area 0 r2(config-router)#redistribute eigrp 100 subnets r2(config-router)#^Z r2#conf t r2(config)#router eigrp 100 r2(config-router)#net 192.1.1.0 r2(config-router)#redistribute ospf 110 metric 1000 100 255 1 1500 r2(config-router)#^Z R3： r3#conf t r3(config)#int f0/0 r3(config-if)#ip add 192.168.13.3 255.255.255.0 r3(config-if)#no sh r3(config-if)#int f1/0 r3(config-if)#ip add 192.1.1.3 255.255.255.0 r3(config-if)#no sh r3(config-if)#^Z r3#conf t r3(config)#router ospf 110 r3(config-router)#router-id 3.3.3.3 r3(config-router)#net 192.168.13.0 0.0.0.255 area 0 r3(config-router)#redistribute eigrp 100 subnets r3(config-router)#^Z r3#conf t r3(config)#router eigrp 100 r3(config-router)#net 192.1.1.0 r3(config-router)#redistribute ospf 110 metric 1000 100 255 1 1500 r3(config-router)#^Z R4： r4#conf t r4(config)#int f0/0 r4(config-if)#ip add 192.1.1.4 255.255.255.0 r4(config-if)#no sh r4(config-if)#int lo 0 r4(config-if)#ip add 4.4.4.4 255.255.255.255 r4(config-if)#^Z r4#conf t r4(config)#router eigrp 100 r4(config-router)#net 192.1.1.0 r4(config-router)#redistribute connected metric 1000 100 255 1 1500 r4(config-router)#^Z 解决需求方案：修改OSPF管理距离 R2： r2#conf t r2(config)#router ospf 110 r2(config-router)#distance 180 3.3.3.3 0.0.0.0 r2(config-router)#^Z R3： r3#conf t r3(config)#router ospf 110 r3(config-router)#distance 180 2.2.2.2 0.0.0.0 r3(config-router)#^Z 实验结果测试： r1#show ip route C 192.168.12.0/24 is directly connected, FastEthernet0/0 1.0.0.0/32 is subnetted, 1 subnets C 1.1.1.1 is directly connected, Loopback0 C 192.168.13.0/24 is directly connected, FastEthernet1/0 4.0.0.0/32 is subnetted, 1 subnets O E2 4.4.4.4 [110/20] via 192.168.13.3, 00:40:15, FastEthernet1/0 [110/20] via 192.168.12.2, 00:40:15, FastEthernet0/0 O E2 192.1.1.0/24 [110/20] via 192.168.13.3, 00:41:55, FastEthernet1/0 [110/20] via 192.168.12.2, 00:41:55, FastEthernet0/0 r2#show ip route C 192.168.12.0/24 is directly connected, FastEthernet0/0 1.0.0.0/32 is subnetted, 1 subnets O E2 1.1.1.1 [110/20] via 192.168.12.1, 00:41:46, FastEthernet0/0 O 192.168.13.0/24 [110/2] via 192.168.12.1, 00:42:11, FastEthernet0/0 4.0.0.0/32 is subnetted, 1 subnets D EX 4.4.4.4 [170/2588160] via 192.1.1.4, 00:42:09, FastEthernet1/0 C 192.1.1.0/24 is directly connected, FastEthernet1/0 r3#show ip route O 192.168.12.0/24 [110/2] via 192.168.13.1, 00:42:55, FastEthernet0/0 1.0.0.0/32 is subnetted, 1 subnets O E2 1.1.1.1 [110/20] via 192.168.13.1, 00:42:55, FastEthernet0/0 C 192.168.13.0/24 is directly connected, FastEthernet0/0 4.0.0.0/32 is subnetted, 1 subnets D EX 4.4.4.4 [170/2588160] via 192.1.1.4, 00:42:54, FastEthernet1/0 C 192.1.1.0/24 is directly connected, FastEthernet1/0 r4#show ip route D EX 192.168.12.0/24 [170/2588160] via 192.1.1.3, 00:43:21, FastEthernet0/0 [170/2588160] via 192.1.1.2, 00:43:21, FastEthernet0/0 1.0.0.0/32 is subnetted, 1 subnets D EX 1.1.1.1 [170/2588160] via 192.1.1.3, 00:43:21, FastEthernet0/0 [170/2588160] via 192.1.1.2, 00:43:21, FastEthernet0/0 D EX 192.168.13.0/24 [170/2588160] via 192.1.1.3, 00:43:21, FastEthernet0/0 [170/2588160] via 192.1.1.2, 00:43:21, FastEthernet0/0 4.0.0.0/32 is subnetted, 1 subnets C 4.4.4.4 is directly connected, Loopback0 C 192.1.1.0/24 is directly connected, FastEthernet0/0 实验结论： 通过修改OSPF通过指定路由器的管理距离，解决负载均衡双点双向重分布。 |
