Packet Tracer 5.0实验(九) 路由器RIP动态路由配置

一、实验目标

? ? ?

掌握RIP协议的配置方法;

掌握查看通过动态路由协议RIP学习产生的路由; 熟悉广域网线缆的连接方式;

二、实验背景

假设校园网通过一台三层交换机连到校园网出口路由器上,路由器再和校园外的另一台路由器连接。现要做适当配置,实现校园网内部主机与校园网外部主机之间的相互通信。为了简化网管的管理维护工作,学校决定采用RIP V2协议实现互通。

三、技术原理

RIP(Routing Information Protocols),路由信息协议,是应用较早、使用较普通的IGP内部网关协议,适用于小型同类网络,是距离矢量协议; RIP协议以跳数衡量路径开销,RIP协议里规定最大跳数为15;

RIP协议有两个版本:RIPv1和RIPv2,RIPv1属于有类路由协议,不支持VLSM,以广播形式进行路由信息的更新,更新周期为30秒;RIPv2属于无类路由协议,支持VLSM,以组播形式进行路由更新。

四、实验步骤

实验拓扑

1、在三层交换机上划分VLAN10和VLAN20,其中VLAN10用于连接校园网主机,VLAN20用于连接R1;

2、路由器之间通过V.35电缆通过串口连接,DCE端连接在R1上,配置其时间频率为64000;

3、主机和交换机通过直连线连接,主机与路由器通过交叉线连接; 4、在S3560上配置RIPv2路由协议; 5、在路由器R1、R2上配置RIPv2路由协议;

6、将PC1、PC2主机默认网关分别设置为与直连网络设备接口IP地址; 7、验证PC1、PC2主机之间可以互相通信; S3560:
