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:
