2.RIPv1与RIPv2共存实验

RIPv1与RIPv2共存实验

1.拓扑图

2.配置解析

在全部路由器上面启用RIP路由协议 左边(R1\\R2\\R5)为RIPv1 右边(R3\\R4\\R5)为RIPv2

下面是各路由器的配置

左边的2台路由器能够接收到R5\\R3\\R4的路由信息 但是却没有R1的信息

右边的2台路由器只能够接收到R5\\R3\\R4的路由信息

为什么会导致这种情况呢?

===================================================================

从上面可以看出

R5给R1发送的信息没有R2的路由信息 R5给R2发送的信息没有R1的路由信息 R5给R3\\R4发送的信息没有R1\\R2的路由信息 原因是因为

*Apr 16 08:17:21.567: RIP: ignored v1 packet from 11.0.0.2 (illegal version) *Apr 16 08:17:51.735: RIP: ignored v1 packet from 12.0.0.2 (illegal version)

说明RIPv1能够接受RIPv2的更新信息 但是RIPv2却不能接受RIPv1的更新信息

我们使用下面的命令在R5上面S1/1和S1/2开启接受v1和v2的RIP信息 Router(config)#int s1/1

Router(config-if)#ip rip receive version 1 2 Router(config-if)#int s1/2

Router(config-if)#ip rip receive version 1 2

实验结果及总结:

RIPv1可以接受RIPv2的路由更新,但是RIPv2却不能接受RIPv1的更新信息,所以 RIPv1和RIPv2可以共存,但是需要让配置了RIPv2的路由器上的与启用RIPv1的 路由器相连的接口上使用

Router(config-if)#ip rip receive version 1 2 来使RIPv2的路由器接受RIPv1的信息
