参考CCIE#9823黄振川的CCNA实验手册(这本实验手册还不错,现在已经绝版了)
RIP(Routing information Protocol)是应用较早、使用较普遍的内部网关协议(Interior Gateway Protocol,简称IGP)，适用于小型同类网络，是典型的距离向量(distance-vector)协议。文档见RFC1058、RFC1723。
RIP通过广播UDP报文来交换路由信息，每30秒发送一次路由信息更新。RIP提供跳跃计数(hop count)作为尺度来衡量路由距离，跳跃计数是一个包到达目标所必须经过的路由器的数目。如果到相同目标有二个不等速或不同带宽的路由器，但跳跃计数相同，则RIP认为两个路由是等距离的。RIP最多支持的跳数为15，即在源和目的网间所要经过的最多路由器的数目为15，跳数16表示不可达。
1.实验目的
通过本实验，读者可以掌握以下技能:
在路由器上启动RIP协议;
声明相应网络进入RIP路由进程;
查看路由表并理解相关字段含义;
查看RIP协议配置信息;
监测RIP协议相关信息。

在R1
、R2
、R3
之间配置RIP V2
协议，并用PING
命令进行PING
测试，使之PING
通。
实验步骤：
1.
在R1.R2.R3
上进行底层配置
R1:
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname router1
router1(config)#int s2/1
router1(config-if)#ip address 12.0.0.1 255.255.255.0
router1(config-if)#no shutdown
router1(config-if)#
R2:
Router>
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname router2
router2(config)#int s2/1
router2(config-if)#ip address 12.0.0.2 255.255.255.0
router2(config-if)#no shutdown
router2(config-if)#^Z
router2#
R3:
Router>
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname router3
router3(config)#int s2/1
router3(config-if)#ip address 23.0.0.3 255.255.255.0
router3(config-if)#no shutdown
router3(config-if)#
*Jun 22 01:04:28.527: %LINK-3-UPDOWN: Interface Serial2/1, changed state to up^Z
router3#
2.
在R1.R2.R3
上配置RIP V2
协议
R1:
router1#
router1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
router1(config)#router rip
router1(config-router)#version 2
router1(config-router)#net 12.0.0.0
router1(config-router)#^Z
router1#
R2:
router2#
router2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
router2(config)#router rip
router2(config-router)#version 2
router2(config-router)#net 12.0.0.0
router2(config-router)#net 23.0.0.0
router2(config-router)#^Z
router2#
R3:
router3#
router3#conf t
Enter configuration commands, one per line. End with CNTL/Z.
router3(config)#router rip
router3(config-router)#version 2
router3(config-router)#net 23.0.0.0
router3(config-router)#^Z
router3#
3.
用show ip route
命令在R1.R2.R3
上查看路由表
R1:
router1#show ip route
