ppp实验

 一.实验拓扑

 二.实验要求

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和R3的ppp进行双向chap验证

三.实验分析、思路、步骤及操作

1.配置IP地址

（1）配置R1的IP地址

[R1]interface serial 1/0/0

[R1-serial1/0/0]ip address 192.168.1.1 24

（2）因为R2和R3捆绑在一起，所以要先做聚合，再配R2的IP地址

[R2]interface serial 1/0/0

[R2-serial1/0/0]ip address 192.168.1.2 24

[R2]interface mp-group 0/0/0 //配置R2的mp 接口

[R2-serial1/0/1]ppp mp mp-group 0/0/0 //将物理接口加入到mp接口

[R2-serial2/0/0]ppp mp mp-group 0/0/0

[R2]interface mp-group 0/0/0

[R2-Mp-group0/0/0]ip address 192.168.2.2 24 //配置R2的IP地址

（3）因为R2和R3捆绑在一起，所以要先做聚合，再配R3的IP地址

[R3]interface mp-group 0/0/0 //配置R3的mp 接口

[R3-serial1/0/0]ppp mp mp-group 0/0/0 //将物理接口加入到mp接口

[R3-serial1/0/1]ppp mp mp-group 0/0/0

[R3]interface mp-group 0/0/0

[R3-Mp-group0/0/0]ip address 192.168.2.3 24 //配置R3的IP地址

2.R2对R1配置认证

[R2]aaa

[R2-aaa]local-user wangdaye password cipher wdy12345

[R2-aaa]local-user wangdaye service-type ppp

[R2-serial1/0/0]ppp authentication-mode chap //配置主验证方

[R1-serial1/0/0]ppp chap user wangdaye

[R1-serial1/0/0]ppp chap password cipher wdy12345 //配置被验证方

[R1-serial1/0/0]shutdown

[R1-serial1/0/0]undo shutdown

3.R2和R3验证之间，R2做主验证方，配置认证

[R2]aaa

[R2-aaa]local-user zhangdaye password cipher zdy12345

[R2-aaa]local-user zhangdaye service-type ppp

[R2-serial1/0/1]ppp authentication-mode chap

[R2-serial2/0/0]ppp authentication-mode chap

[R3-serial1/0/0]ppp chap user zhangdaye

[R3-serial1/0/0]ppp chap password cipher zdy12345

[R3-serial1/0/1]ppp chap user zhangdaye

[R3-serial1/0/1]ppp chap password cipher zdy12345

[R3-serial1/0/1]shutdown

[R3-serial1/0/1]undo shutdown

[R3-seize1/0/0]shutdown

[R3-serial1/0/0]undo shutdown

4.R2和R3验证之间，R3做主验证方，配置认证

[R3]aaa

[R3-aaa]local-user liudaye password cipher ldy12345

[R3-aaa]local-user liudaye service-type ppp

[R3-serial1/0/0]ppp authentication-mode chap

[R3-serial1/01]ppp authentication-mode chap

[R2-serial1/0/1]ppp chap user liudaye

[R2-serial1/0/1]ppp chap password cipher ldy12345

[R2-serial2/0/0]ppp chap user liudaye

[R2-serial2/0/0]ppp chap password cipher ldy12345

[R2-serial2/0/0]shutdown

[R2-serial2/0/0]undo shutdown

[R2-serial1/0/1]shutdown

[R2-serial1/0/1]undo shutdown
