1、跟据拓扑图拖动R、S、PC到工作区
2、配置PC和R，然后连线（连线的时候请记录所选接口）,如上图
3、配置交换机
%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up

Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.

路由器的基本配置
R1
R2
配置RIP V2协议：
配置S3550上RIP V2协议
s3550#enable
s3550#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
s3550(config)#router rip
s3550(config-router)#network 172.16.1.0
s3550(config-router)#network 172.16.2.0
s3550(config-router)#version 2
s3550(config-router)#no auto-summary
s3550(config-router)#
配置R1上RIP V2协议
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface FastEthernet0/0
Router(config-if)#no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

同理配置R2上RIP V2协议（也可直接在配置菜单里做）
