实验7:RIP 路由协议的配置
一、实验目的
1、练习RIP 动态路由协议的基本配置;
2、掌握了解RIP 路由协议原理
二、实验环境:
Packet tracer 5.0
三、关于RIP 的基础知识
RIP(Routing Information Protocol)是最常使用的内部网关协议(Interior Gateway Protocol)之一,是一种典型的基于D-V 算法的动态路由协议。
通过UDP(User Datagram Protocol)报文交换路由信息,使用跳数(Hop Count)来衡量到达目的地的距离(被称为路由权-Routing cost)。
由于在RIP 中大于或等于16 的跳数被定义为无穷大(即目的网络或主机不
可达),所以RIP 一般用于采用同类技术的中等规模的网络,如校园网及一个地区范围内的网络,RIP 并非为复杂、大型的网络而设计。
启动RIP,进入RIP 视图:router Rip
关闭RIP:no rip
在指定的网络上使能RIP network{ network-number| all }
在指定的网络上禁用RIP no network{ network-number| all
四:实验步骤:
拓扑图如下所示:
配置过程:
Router1:
Router>enable //进入特权模式
Router#conf ter //进入全局配置模式
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int f0/0 //配置Fa0/0 接口
Router(config-if)#ip add 1.1.1.2 255.255.255.0
Router(config-if)#no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
Router(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
Router(config-if)#exit
Router(config)#int s0/0/0 //配置串口
Router(config-if)#ip add 1.1.6.1 255.255.255.0
Router(config-if)#clock rate 64000
Router(config-if)#no shutdown
%LINK-5-CHANGED: Interface Serial0/0/0, changed state to down
Router(config-if)#exit
Router(config)#int s0/0/1 //配置串口
Router(config-if)#ip add 1.1.2.1 255.255.255.0
Router(config-if)#clock rate 64000
Router(config-if)#no shutdown
%LINK-5-CHANGED: Interface Serial0/0/1, changed state to down
Router(config-if)#exit
Router(config)#router rip //进入RIP 视图
Router(config-router)#network 1.0.0.0 //发布直连网络
Router(config-router)#exit
Router(config)#exit
Router#
%SYS-5-CONFIG_I: Configured from console by console
Router#show ip route //查看路由表
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

Gateway of last resort is not set
1.0.0.0/24 is subnetted, 1 subnets
C 1.1.1.0 is directly connected, FastEthernet0/0
