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对R3的 PPP进行双向 chap 验证

三、实验步骤

R1:

[R1]int s3/0/0
[R1-Serial3/0/0]ip add	
[R1-Serial3/0/0]ip address 192.168.1.1 24

R2:

[R2]int s3/0/0
[R2-Serial3/0/0]ip add	
[R2-Serial3/0/0]ip address 192.168.1.2 24

对R2和R3进行捆绑为 PPP MP 直连：

R2:

[R2]int Mp-group 0/0/1
[R2-Mp-group0/0/1]ip address 192.168.2.1 24
[R2-Mp-group0/0/1]int s3/0/1
[R2-Serial3/0/1]ppp mp Mp-group 0/0/1
[R2-Serial3/0/1]int s4/0/0
[R2-Serial4/0/0]ppp mp Mp-group 0/0/1

R3：

[R3]int Mp-group 0/0/1
[R3-Mp-group0/0/1]ip address 192.168.2.2 24
R3-Mp-group0/0/1]int s3/0/0
[R3-Serial3/0/0]ppp mp Mp-group 0/0/1
[R3-Serial3/0/0]int s3/0/1
[R3-Serial3/0/1]pp mp Mp-group 0/0/1

ppp验证的chap：R2对R1

R2：

[R2]aaa
[R2-aaa]local-user ck password cipher 123 privilege level 15
[R2-aaa]local-user ck service-type ppp
[R2-aaa]int s3/0/0
[R2-Serial3/0/0]ppp authentication-mode chap        #设置验证类型

R1:

[R1]int s3/0/0
[R1-Serial3/0/0]ppp chap user ck
[R1-Serial3/0/0]ppp chap password cipher 123

ppp验证的chap：R2对R3的 PPP进行双向 chap 验证

R2:

[R2-aaa]local-user hh password cipher 789 privilege level 15
[R2-Serial3/0/1]ppp authentication-mode chap 
[R2-Serial4/0/0]pp authentication-mode chap


[R2]int s3/0/1
[R2-Serial3/0/1]ppp chap user cc
[R2-Serial3/0/1]ppp chap password cipher 456
[R2-Serial3/0/1]int s4/0/0
[R2-Serial4/0/0]ppp chap user cc
[R2-Serial4/0/0]ppp chap password cipher 456

R3：

[R3]aaa
[R3-aaa]local-user cc password cipher 456 privilege level 15
[R3-aaa]local-user cc service-type ppp
#分别对两个物理口进行验证类型
[R3-aaa]int s3/0/1
[R3-Serial3/0/1]ppp authentication-mode chap
[R3]int s3/0/0
[R3-Serial3/0/0]ppp authentication-mode chap


[R3]int s3/0/0
[R3-Serial3/0/0]ppp chap user hh
[R3-Serial3/0/0]ppp chap password cipher 789

[R3-Serial3/0/0]int s3/0/1	
[R3-Serial3/0/1]ppp chap user hh	
[R3-Serial3/0/1]ppp chap password cipher 789

关闭一个R3的逻辑口再打开双UP完成双向
