一、实验拓扑图

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、实验步骤

1、PPP MP：

（1）R2配置：

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

[R2]int s 3/0/1

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

[R2-Serial3/0/1]int s4/0/0        

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

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

[R2-Mp-group0/0/0]ip add        

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

R3配置：

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

[R3-Mp-group0/0/0]int s3/0/0

[R3-Serial3/0/0]ppp mp MP        

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

[R3-Serial3/0/0]int s3/0/1

[R3-Serial3/0/1]ppp mp MP        

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

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

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

2、配置IP地址：

R1：

[R1]int s3/0/0

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

R2：

[R2]int s3/0/0        

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

3、R2对R1的 PPP 单向chap验证

R2（主验证方）：

[R2]aaa

[R2-aaa]loc        

[R2-aaa]local-user wang pas        

[R2-aaa]local-user wang password ci        

[R2-aaa]local-user wang password cipher w12345

Info: Add a new user.

[R2-aaa]loc        

[R2-aaa]local-user wang se        

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

[R2]int s4/0/0

[R2-Serial4/0/0]ppp au        

[R2-Serial4/0/0]ppp authentication-mode chap

R1（被验证方）：

[R1]int s 3/0/0

[R1-Serial3/0/0]ppp chap us        

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

[R1-Serial3/0/0]ppp chap pass        

[R1-Serial3/0/0]ppp chap password ci        

[R1-Serial3/0/0]ppp chap password cipher w12345

4、R2和R3 PPP 双向验证

（1）R2为主验证方

R2配置：

[R2]aaa

[R2-aaa]local-user li pass        

[R2-aaa]local-user li password ci        

[R2-aaa]local-user li password cipher l12345

Info: Add a new user.

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

[R2]int s3/0/1

[R2-Serial3/0/1]ppp au        

[R2-Serial3/0/1]ppp authentication-mode chap

[R2-Serial3/0/1]int s4/0/0

[R2-Serial4/0/0]ppp au                

[R2-Serial4/0/0]ppp authentication-mode chap

R3配置：

[R3]int s3/0/0        

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

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

[R3-Serial3/0/0]ppp chap password cipher l12345

[R3]int s3/0/1        

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

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

[R3-Serial3/0/1]ppp chap password cipher l12345

（2）R3为主验证方

R3配置：

[R3]aaa

[R3-aaa]local-user zhao password cipher z123456

Info: Add a new user.        

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

[R3-aaa]int s3/0/0        

[R3-Serial3/0/0]ppp authentication-mode chap

[R3]int s3/0/1

[R3-Serial3/0/1]ppp authentication-mode chap

R2配置：

[R2]int s3/0/1

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

[R2-Serial3/0/1]ppp chap password cipher z123456

[R2]int s4/0/0
