拓扑图

• 实验步骤

1. 配置IP地址及创建mp逻辑口

[R1]int ser 3/0/0

[R1-Serial3/0/0]ip add 192.168.1.1 24

[R1-Serial3/0/0]

[R2]int se3/0/0

[R2-Serial3/0/0]ip add 192.168.1.2 24

[R2-Serial3/0/0]int mp

[R2-Serial3/0/0]int mp-g

[R2-Serial3/0/0]int mp-group 0/0/0

[R2-Mp-group0/0/0]

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

[R3-Mp-group0/0/0]

2.将路由口加入逻辑口

[R2-Mp-group0/0/0]int se3/0/1

[R2-Serial3/0/1]ppp mp Mp-group 0/0/0

[R2-Serial3/0/1]int se4/0/0

[R2-Serial4/0/0]ppp mp Mp-group 0/0/0

[R3-Mp-group0/0/0]int se3/0/0

[R3-Serial3/0/0]ppp mp mp-group 0/0/0

[R3-Serial3/0/0]int se3/0/1

[R3-Serial3/0/1]ppp mp mp-group 0/0/0

[R3-Serial3/0/1]

3.进入逻辑口配地址

[R2]int Mp-group 0/0/0

[R2-Mp-group0/0/0]ip add 192.168.2.2 24

[R2-Mp-group0/0/0]

[R3]int Mp-group 0/0/0

[R3-Mp-group0/0/0]ip add 192.168.2.3 24

[R3-Mp-group0/0/0]

4.R2对R1的PPP进行单向chap验证（表明R2是主验证方，R1是被验证方）

在R2上创建用于验证R1的用户，并在接口配置chap验证方式

[R2]aaa

[R2-aaa]local-user wangdaye password cipher 123456

Info: Add a new user.

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

[R2-aaa]int se3/0/0

[R2-Serial3/0/0]ppp authentication-mode chap

[R2-Serial3/0/0]

在R1连接R2的接口上配置用于验证的用户名和密码

[R1-Serial3/0/0]ppp chap user wangdaye

[R1-Serial3/0/0]ppp chap password cipher 123456

[R1-Serial3/0/0]

5.R2和R3的PPP进行双向chap验证

R2做主验证方

[R2]aaa

[R2-aaa]lo wangdaye pass ci 123456

[R2-aaa]lo wangdaye ser ppp

[R2-aaa]int se3/0/1

[R2-Serial3/0/1]ppp au chap

[R2-Serial3/0/1]int se4/0/0

[R2-Serial4/0/0]ppp au chap

[R2-Serial4/0/0]

[R3]int se3/0/0

[R3-Serial3/0/0]ppp chap user wangdaye

[R3-Serial3/0/0]ppp chap pass cip 123456

[R3-Serial3/0/0]int se3/0/1

[R3-Serial3/0/1]ppp chap user wangdaye

[R3-Serial3/0/1]ppp chap pass cip 123456

[R3-Serial3/0/1]

R3做主验证方

[R3]aaa

[R3-aaa]lo wangdaye pass cip 123456

Info: Add a new user.

[R3-aaa]lo wangdaye ser ppp

[R3-aaa]int se3/0/0

[R3-Serial3/0/0]ppp au chap

[R3-Serial3/0/0]int se3/0/1

[R3-Serial3/0/1]ppp au chap

[R3-Serial3/0/1]

[R2]int se3/0/1

[R2-Serial3/0/1]ppp chap user wangdaye

[R2-Serial3/0/1]ppp chap pass cip 123456

[R2-Serial3/0/1]int se4/0/0

[R2-Serial4/0/0]ppp chap user wangdaye

[R2-Serial4/0/0]ppp chap pass cip 123456

[R2-Serial4/0/0]
