RIP_路由协议的配置

RIP 路由协议的配置

一、实验目的

1、复习路由器的三种模式及口令管理

2、练习RIP 动态路由协议的基本配置;

3、掌握了解RIP 路由协议原理

二、实验环境:

Cisco Packet Tracer

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:

绘制拓扑图如下所示(为每个路由器添加一个WIC-2T模块):

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)#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)#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

E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP

i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area * - candidate default, U - per-user static route, o - ODR

P - periodic downloaded static route

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

Router#

Router2:

Router>enable

Router#conf ter

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#int f0/0

Router(config-if)#ip add 1.1.5.2 255.255.255.0

Router(config-if)#no shutdown

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

Router(config-if)#exit

Router(config)#int s0/0/1

Router(config-if)#ip add 1.1.2.2 255.255.255.0

Router(config-if)#clock rate 64000

Router(config-if)#no shutdown

%LINK-5-CHANGED: Interface Serial0/0/1, changed state to up

Router(config-if)#exit

Router(config)#int s0/0/0

Router(config-if)#ip add 1.1.3.1 255.255.255.0
