ensp ppp验证实验(二)

1,实验拓扑 

2,实验目的 

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

3,实验过程

1,R1和R2使用PPP链路直连
R1:
 
<Huawei>sys
 
[Huawei]sysname R1
 
[R1]int Serial 3/0/0
 
[R1-Serial3/0/0]ip add 192.168.1.1 24
 
 
 R2:
 
[Huawei]sysname R2
 
[R2]int Serial 3/0/0
 
[R2-Serial3/0/0]ip add 192.168.1.2 24
2,R2和R3把2条PPP链路捆绑为PPP  MP直连
​
R2:
 
[R2]interface Mp-group 0/0/0
 
[R2-Mp-group0/0/0]q
 
[R2]int Serial 3/0/1
 
[R2-Serial3/0/1]ppp mp Mp-group 0/0/0
 
[R2-Serial3/0/1]q
 
[R2]int Serial 4/0/0
 
[R2-Serial4/0/0]ppp mp Mp-group 0/0/0
 
[R2]interface Mp-group 0/0/0
 
[R2-Mp-group0/0/0]ip add 192.168.2.2 24
 
[R2]display ip interface brief
 
R3:
 
[Huawei]sysname R3
 
[R3]int Mp-group 0/0/0
 
[R3-Mp-group0/0/0]q
 
[R3]int Serial 3/0/0
 
[R3-Serial3/0/0]ppp mp Mp-group 0/0/0
 
[R3-Serial3/0/0]q
 
[R3]int Serial 3/0/1
 
[R3-Serial3/0/1]ppp mp Mp-group 0/0/0
 
[R3-Mp-group0/0/0]ip add 192.168.2.3 24
 
[R3]display ip interface brief
 
[R2]ping 192.168.2.3
 
  PING 192.168.2.3: 56  data bytes, press CTRL_C to break
 
    0.00% packet loss
3,R2 对 R1 的 PPP 进行单向 chap 验证

分析:R2 对 R1 进行单向验证,表示 R2 是主验证方,R1 是被验证方。所以需要在 R2 上创建用于验证的用户(用户名:jo;密码:1234567)

主验证方配置:

[R2]aaa
 
[R2-aaa]local-user jo password cipher 1234567
 
[R2-aaa]local-user jo service-type ppp
 
[R2-aaa]q
 
[R2]int Serial 3/0/0
 
[R2-Serial3/0/0]ppp authentication-mode chap

 被验证方配置:

[R1]int Serial 3/0/0
 
[R1-Serial3/0/0]ppp chap user jo
 
[R1-Serial3/0/0]ppp chap password cipher 1234567
4,R2对R3的PPP进行双向chap验证
R2为主验证方,R3为被验证方
​[R2]aaa
 
[R2-aaa]local-user j password cipher 1234567
 
[R2-aaa]q
 
[R2]int Serial 3/0/1
 
[R2-Serial3/0/1]ppp authentication-mode chap
 
[R2-Serial3/0/1]q
 
[R2]int Serial 4/0/0
 
[R2-Serial4/0/0]ppp authentication-mode chap

​
[R3]int Serial 3/0/0
 
[R3-Serial3/0/0]ppp chap user j
 
[R3-Serial3/0/0]ppp chap password cipher 1234567
 
[R3-Serial3/0/0]q
 
[R3]int Serial 3/0/1
 
[R3-Serial3/0/1]ppp chap user j
 
[R3-Serial3/0/1]ppp chap password cipher 1234567
R3为主验证方,R2为被验证方
[R3]aaa
 
[R3-aaa]local-user jyh password cipher 1234567
 
[R3-aaa]q
 
[R3]int s 3/0/0
 
[R3-Serial3/0/0]ppp authentication-mode chap
 
[R3-Serial3/0/0]q
 
[R3]int s 3/0/1
 
[R3-Serial3/0/1]ppp authentication-mode chap
[R2]int s 3/0/1
 
[R2-Serial3/0/1]ppp chap user jyh
 
[R2-Serial3/0/1]ppp chap password cipher 1234567
 
[R2-Serial3/0/1]q
 
[R2]int s 4/0/0
 
[R2-Serial4/0/0]ppp chap user jyh
 
[R2-Serial4/0/0]ppp chap password cipher 1234567
