1、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，
2、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
3、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:SwitchSwitchenSwitch#conf tEnter configuration commands, one per line.
