路由策略3：Distribute-list6在双点双向重分发中的应用


拓扑图：
如上图，在R2和R4上配置双点双向重发布，在配置双点双向重发布时，小AD重发布进大AD时是没问题的，但是大AD重发布进小AD时，就会出现问题，例如次优路径，环路等，如上图，如果是R2先学习到RIP网络的路由，那么在R4的路由表中，RIP网络的路由将是**OSPF学习到的，这样就产生了次优路径（不是**优的路由）！可以配置分发列表来避免次优路径！下面先不配置分发列表，查看各路由器的路由表，接下来好做实验：
配置参数：
R2:
router ospf 1
redistribute rip metric 12 subnets
 network 2.2.2.0 0.0.0.255 area 0
router rip
 version 2
 redistribute ospf 1 metric 3
 network 1.0.0.0
 no auto-summary
R4:
router ospf 1
redistribute rip metric 12 subnets
 network 4.4.4.0 0.0.0.255 area 0
router rip
 version 2
 redistribute ospf 1 metric 3
 network 3.0.0.0
 no auto-summary
查看路由表：
R1:
r1#sh ip rou

R       10.9.9.9/32 [120/3] via 3.3.3.2, 00:00:13, Serial0/1
                    [120/3] via 1.1.1.2, 00:00:20, Serial0/0
C       10.2.0.0/16 is directly connected, Loopback1

C       10.1.0.0/16 is directly connected, Loopback0
r1#
可以看到R1学习到的OSPF的路由是**两台边界路由器R2和R4学习来的，而且实现了负载均衡。这里R2和R4是将OSPF重发布进RIP，是小AD重发布进大AD，不会出现问题。
R2:

R       10.3.0.0/16 [120/1] via 1.1.1.1, 00:00:23, Serial0/0
R       10.1.0.0/16 [120/1] via 1.1.1.1, 00:00:23, Serial0/0
r2#
可以看到R2**RIP学习到了RIP网络的路由！
R3:

r3#
可以看到R3是**R2来学习RIP网络的路由的！！！
R4:

O E2    10.1.0.0/16 [110/12] via 4.4.4.1, 00:05:51, Serial0/0
r4#
如上面，R4是**OSPF学习到的RIP网络的路由，因为OSPF的AD值比RIP小，所以OSPF的路由信息被装进路由表，而这并不**优的路由，这就是大AD值在重发布进小AD值时遇到的次优路径。下面配置分发列表来解决这个问题：
配置参数：
R2:
r2(config)#acc 1 de 10.1.0.0  //配置不匹配RIP网络的路由
r2(config)#acc 1 de 10.2.0.0
r2(config)#acc 1 de 10.3.0.0
r2(config)#acc  1 per an  //配置匹配其它的路由
r2(config)#router os 1 //进入OSPF路由配置进程
r2(config-router)#distribute-list 1 in s0/1 //配置分发列表，只有访问列表1匹配的路由才可以从接口s0/1进入
R4:
r4(config)#acc 1 de 10.1.0.0
r4(config)#acc 1 de 10.2.0.0
r4(config)#acc 1 de 10.3.0.0
r4(config)#acc 1 per an
r4(config)#router os 1
r4(config-router)#distri 1 in s0/0
r4(config-router)#
查看配置效果：
R2:
r2#sh ip rou

R       10.1.0.0/16 [120/1] via 1.1.1.1, 00:00:42, Serial0/0
r2#
可以看出R2**RIP学习到了RIP网络的路由
R3:

r3#
可以看到R3的路由表中，RIP网络的路由是**R2和R4学习到的而且实现了负载均衡，和R1学习到OSPF网络的路由一样，可以看到有2条路由去往对端的网络！！！
R4:
r4#sh ip rou
     1.0.0.0/24 is subnetted, 1 subnets

R       10.1.0.0/16 [120/1] via 3.3.3.1, 00:00:21, Serial0/1
r4#
可以看到R4是**RIP学习到的RIP网络的路由，而不是**OSPF，这样避免了次优路径！
