目录

实验要求：

​编辑需求分析：

实验配置：

1.R2和R3，配置PPP mp

2.配置IP地址，测试R1，R2是否联通

3.R2对R1的PPP进行单向的CHAP验证

4.R2,R3的PPP进行双向CHAP验证

---

实验要求：

需求分析：

1.R1和R2使用PPP链路直连,R2和R3两条PPP链路为PPP MP直连。

2.创建MP-group接口，加入MP-group组，在逻辑接口配置IP地址。

3.配置R1,R2接口IP。

4.R2对R1的PPP进行单向的CHAP验证。

5.R2和R3的PPP进行双向的CHAP验证，配置四次。

6.如果配置的PPP mp链路需要做PPP的认证，则主验证方和被验证方的接口验证配置，应该再正是的物理接口下进行配置。

实验配置：

1.R2和R3，配置PPP mp

[AR2]interface Mp-group0/0/0
[AR2]int s3/0/1
[AR2-Serial3/0/1]ppp mp Mp-group0/0/0
[AR2-Serial3/0/1]int s4/0/0
[AR2-Serial4/0/0]ppp mp Mp-group0/0/0


[AR2]interface Mp-group0/0/0
[AR2]int s3/0/1
[AR2-Serial3/0/1]ppp mp Mp-group0/0/0
[AR2-Serial3/0/1]int s4/0/0
[AR2-Serial4/0/0]ppp mp Mp-group0/0/0

2.配置IP地址，测试R1，R2是否联通

[AR1]int s3/0/0
[AR1-Serial3/0/0]ip address 192.168.1.1 24

[AR2]int s3/0/0
[AR2-Serial3/0/0]ip address 192.168.1.2 24

[AR2]interface Mp-group0/0/0
[AR2-Mp-group0/0/0]ip address 192.168.2.2 24

[AR3]interface Mp-group0/0/0
[AR3-Mp-group0/0/0]ip address 192.168.2.3 24

3.R2对R1的PPP进行单向的CHAP验证

在R2的Serrial3/0/0接口上设置验证类型(主验证方：配置用户列表及验证方式)
[AR2]aaa
[AR2-aaa]local-user zz password cipher 123
Info: Add a new user.
 
[AR2-aaa]local-user zz service-type ppp
[AR2-aaa]int s3/0/0
[AR2-Serial3/0/0]ppp authentication-mode chap     # 设置验证类型


在R1的Serial3/0/0接口上配置用于验证的用户名和密码
[AR1]int s3/0/0
[AR1-Serial3/0/0]ppp chap user zll
[AR1-Serial3/0/0]ppp chap password cipher 1214

4.R2,R3的PPP进行双向CHAP验证

R2先作为主认证方
[AR2]aaa
[AR2-aaa]local-user zz password cipher 123
[AR2-aaa]local-user zz service-type ppp
[AR2-aaa]int s3/0/1
[AR2-Serial3/0/1]ppp authentication-mode chap
[AR2-Serial3/0/1]link-protocol ppp 
[AR2-Serial3/0/1]int s4/0/0
[AR2-Serial4/0/0]ppp authentication-mode chap
[AR2-Serial4/0/0]link-protocol ppp
  
R3作为被认证方
[AR3]int s3/0/0
[AR3-Serial3/0/0]ppp chap user zz
[AR3-Serial3/0/0]ppp chap password cipher 123
[AR3-Serial3/0/0]int s3/0/1
[AR3-Serial3/0/1]ppp chap user zz
[AR3-Serial3/0/1]ppp chap password cipher 123

R3作为认证方
[AR3]aaa
[AR3-aaa]local-user zz password cipher 123
[AR3-aaa]local-user zz service-type ppp
[AR3-aaa]int s3/0/0
[AR3-Serial3/0/0]ppp authentication-mode chap 
[AR3-Serial3/0/0]link-protocol ppp
[AR3-Serial3/0/0]int s3/0/1
[AR3-Serial3/0/1]ppp authentication-mode chap
[AR3-Serial3/0/1]link-protocol ppp
 
R2作为被认证方
[AR2]int s3/0/1
[AR2-Serial3/0/1]ppp chap user zz
[AR2-Serial3/0/1]ppp chap password cipher 123
[AR2-Serial3/0/1]int s4/0/0
[AR2-Serial4/0/0]ppp chap user zz
[AR2-Serial4/0/0]ppp chap password cipher 123

接口处shutdown后undo shutdown，看是否有两次开启信息，若有，即配置成功
