实验二配置RIP协议和简单路由练习（4课时）

    一．实训目的：

    1．掌握RIP（路由选择信息协议）协议的基本配置与验证。

    二．实训内容

    1．通过对RIP路由选择协议的配置，实现全网的连通；

    2．声明相应网络进入RIP路由进程；

    3．查看路由表并理解相关字段含义；

    三．实训环境的搭建

    1.准备PC机1台，操作系统为Windows2000Professional；

    2.准备Cisco2621XM路由器3台，分别为R1、R2和R3；

    3．WIC-1T模块6个；

    4．V.35DTE电缆3条，V.35DCE电缆3条；

    5.Console电缆1条,通过Console电缆把PC机的COM端口和路由器的Console端口连接起来,配置路由器;

    四．实训操作实践与步骤

    1．查DTE/DCE电缆

     上述结果表明RIP协议工作的特点如下：

更新信息缺省情况下向所有参与路由的接口发送；RIP协议版本1的更新包是广播包（sendingv1updateto255.255.255.255），

     RIP把整个路由表向相邻路由器发送；当前所有接口发送和接收的RIP更新包的版本均为1。

9.假定网络中的路由器B的路由表有如下的项目（这三列分别表示“目的网络”、“距离”和“下一跳路由器”）

N1　　　7　　A

N2　　　2　　C

N6　　　8　　F

N8　　　4　　E

N9　　　4　　F

现在B收到从C发来的路由信息（这两列分别表示“目的网络”和“距离”　）：

N2　　　4

N3　　　8　　

N6　　　4　　

N8　　　3

N9　　　5　　

试求出路由器B更新后的路由表。

解：

路由器B更新后的路由表如下：
