PPP实验笔记

一、实验拓扑

二、实验需求

1. R1和R2使用 PPP链路直连，R2 和 R3 把2条 PPP链路捆绑为 PPP MP 直连
2. 按照图示配置 IP地址
3. R2对R1的PPP进行单向chap验证
4. R2对R3的PPP进行双向chap验证

三、实验思路

1. IP地址配置
2. 做chap验证

四、实验步骤

1.配置IP地址

[r1]int S4/0/0[r1-Serial4/0/0]ip add 192.168.1.1 24

[r2]int S4/0/0[r1-Serial4/0/0]ip add 192.168.1.2 24

#将R2和R3的两条PPP链路捆绑，并配置其IP地址

[r2]int Mp-group 0/0/0[r2-Mp-group0/0/0]ip add 192.168.2.1 24[r3]int Mp-group 0/0/0[r3-Mp-group0/0/0]ip add 192.168.2.2 24[r3-Mp-group0/0/0]q

[r3]int s4/0/0 [r3-Serial4/0/0]ppp mp Mp-group 0/0/0.[r3-Serial4/0/0]int s3/0/0[r3-Serial3/0/0]ppp mp Mp-group 0/0/0

2.做chap验证

#R2对R1的单向chap验证，R2对主验证方，R1为被验证方

[r2]aaa[r2-aaa]local-user wangdaye password cipher 123456 privilege level 15Info: Add a new user.[r2-aaa]local-user wangdaye service-type ppp[r2-aaa]q[r2]int s4/0/0[r2-Serial4/0/0]ppp authentication-mode chap[r2-Serial4/0/0]q

#R2对R3进行双向chap验证，R2为主验证方时，

#R3为被验证方

[r3]int s4/0/0[r3-Serial4/0/0]ppp chap user zhangdaye[r3-Serial4/0/0]ppp chap password cipher 123456[r3-Serial4/0/0]int s3/0/0 [r3-Serial3/0/0]ppp chap user zhangdaye[r3-Serial3/0/0]ppp chap password cipher 123456[r3-Serial3/0/0]q

#R3为主验证方时
