实验五：RIP动态路由的配置

实验五：RIP动态路由的配置

实验介绍：

本实验所用的设备为：三台带有2个S0口和一个E0口的路由器，三台PC

实验目的：

灵活掌握RIP的动态路由的配置。

(注:网络拓扑图见实验一附件)

实验步骤：

1.         R1上的配置：

Router>

Router>en

Router#conf t

Router(config)#host r1

r1(config)#int e0

r1(config-if)#ip add 172.16.1.1 255.255.255.0

r1(config-if)#no shutdown

r1(config-if)#exit

r1(config)#int s0

r1(config-if)#ip add 172.16.2.1 255.255.255.0

r1(config-if)#no shutdown

r1(config-if)#clock rate 56000

r1(config-if)#no shutdown

r1(config-if)#exit

r1(config)#router rip

r1(config-router)#net 172.16.0.0

r1(config-router)#^Z

RIP协议启用前的路由表

r1#show ip route

Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

       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, * - candidate default

       U - per-user static route

Gateway of last resort is not set

C      172.16.1.0/24 is directly connected, Ethernet0

4.         测试：

r1#

r1#ping

Protocol [ip]:

Target IP address: 172.16.5.2

Repeat count [5]:

Datagram size [100]:

Timeout in seconds [2]:

Extended commands [n]:

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 172.16.5.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

PC 上的配置为：

PC1：IP为172.16.1.2 网关：172.16.1.1

PC2：IP为172.16.3.2 网关：172.16.3.1

PC3：IP为172.16.5.2 网关：172.16.5.1
