PPP实验笔记
一、实验拓扑
二、实验需求
- 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
- 按照图示配置 IP地址
- R2对R1的PPP进行单向chap验证
- R2对R3的PPP进行双向chap验证
三、实验思路
- IP地址配置
- 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 0/0/02.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
