CCNA学习笔记26--RIP版本1与版本2兼容(实验）

实验目的：熟练掌握RIP的版本1与版本2的共存问题
实验拓扑：

实验步骤
1.基本配置
2.配置端口ip

3.在R3上配置RIPv1在R1 R2上配置RIPv2
R1(config)#router rip
R1(config-router)#version 2
R1(config-router)#no auto-summary
R1(config-router)#network 11.0.0.0
R1(config-router)#network 12.0.0.0

R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#no auto-summary
R2(config-router)#network 22.0.0.0
R2(config-router)#network 12.0.0.0
R2(config-router)#network 23.0.0.0

R3(config)#router rip
R3(config-router)#version 1
R3(config-router)#network 33.0.0.0
R3(config-router)#network 23.0.0.0

4.检查
R3#show ip route
C        23.1.1.0/24 is directly connected, Ethernet0/0
C        33.1.1.0/24 is directly connected, Loopback0
//在R3上，发现已经没有学到RIP的路由

R2#show ip route
R        11.1.1.0 [120/1] via 12.1.1.1, 00:00:04, Ethernet0/0
      12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        12.1.1.0/24 is directly connected, Ethernet0/0
C        22.1.1.0/24 is directly connected, Loopback0
C        23.1.1.0/24 is directly connected, Ethernet0/1
//在R2上也学不到R3的路由

4.在R2的与R3连接的端口做配置，不再发送和接受RIPv2的更新，而是发送和接受RIPv1的更新。实现R2的RIPv2与R3的RIPv1的兼容
R2(config)#interface ethernet 0/1
R2(config-if)#ip rip send version 1
R2(config-if)#ip rip receive version 1

R2#show ip route
R        11.1.1.0 [120/1] via 12.1.1.1, 00:00:29, Ethernet0/0
      12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
R     33.0.0.0/8 [120/1] via 23.1.1.3, 00:00:22, Ethernet0/1
C        12.1.1.0/24 is directly connected, Ethernet0/0
C        22.1.1.0/24 is directly connected, Loopback0
C        23.1.1.0/24 is directly connected, Ethernet0/1
R3#show ip route
R     11.0.0.0/8 [120/2] via 23.1.1.2, 00:00:00, Ethernet0/0
R     12.0.0.0/8 [120/1] via 23.1.1.2, 00:00:00, Ethernet0/0
R     22.0.0.0/8 [120/1] via 23.1.1.2, 00:00:00, Ethernet0/0
      23.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        23.1.1.0/24 is directly connected, Ethernet0/0
C        33.1.1.0/24 is directly connected, Loopback0
