ppp协议

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和R3的PPP进行双向chap验证

三.实验思路

1.R2对R1进行ppp单向chap验证：

R2配置为主，R1配置为被

2.配置R2与R3之间的ppp MPR2和R3进行ppp双向chap验证：

R2，R3都要配置主被

四.实验步骤

1.R1与R2的链路直连

//路由器R1的配置
[Huawei]sysname R1
[R1]int s 3/0/0
[R1-Serial3/0/0]ip ad 192.168.1.1 24

//路由器R2的配置
[Huawei]sysname R2
[R2]int s 3/0/0
[R2-Serial3/0/0]ip address 192.168.1.2 24
[R2]aaa
[R2-aaa]local-user rjw password cipher 123456
Info: Add a new user.
[R2-aaa]local-user rjw service-type ppp
[R2]int s 3/0/0
[R2-Serial3/0/0]ppp authentication-mode chap
[R2-Serial3/0/0]link-protocol ppp

//R1进行ppp验证
[R1]int s 3/0/0
[R1-Serial3/0/0]ppp chap user rjw
[R1-Serial3/0/0]ppp chap password cipher 123456

2.MP-GROUP的配置

[R2]int Mp-group 0/0/0
[R2-Mp-group0/0/0]ip address 192.168.2.2 24
[R2-Mp-group0/0/0]int s 3/0/1
[R2-Serial3/0/1]ppp mp Mp-group 0/0/0
[R2-Serial3/0/1]int s 4/0/0
[R2-Serial4/0/0]ppp mp Mp-group 0/0/0

[R3]int Mp-group 0/0/0
[R3-Mp-group0/0/0]int s 3/0/0
[R3-Serial3/0/0]ppp mp Mp-group 0/0/0
[R3-Serial3/0/0]int s 3/0/1
[R3-Serial3/0/1]ppp mp Mp-group 0/0/0
[R3-Serial3/0/0]int mp-group 0/0/0
[R3-Mp-group0/0/0]ip address 192.168.2.3 24

3.R2与R3进行ppp双向chap验证:

//R2主
[R2]aaa
[R2-aaa]local-user rjw password cipher 123456
[R2-aaa]local-user rjw service-type ppp
[R2-aaa]int s 3/0/1
[R2-Serial3/0/1]ppp authentication-mode chap
[R2-Serial3/0/1]link-protocol ppp
[R2-Serial3/0/1]int s 4/0/0
[R2-Serial4/0/0]ppp authentication-mode chap
[R2-Serial4/0/0]link-protocol ppp
//R3验证
[R3]int s 3/0/0
[R3-Serial3/0/0]ppp chap user rjw
[R3-Serial3/0/0]ppp chap password cipher 123456
[R3]int s 3/0/1
[R3-Serial3/0/0]ppp chap user rjw
[R3-Serial3/0/0]ppp chap password cipher 123456

//R3主
[R3]aaa
[R3-aaa]local-user rjw password cipher 123456
Info: Add a new user.
[R3-aaa]local-user rjw service-type ppp
[R3-aaa]int s 3/0/0
[R3-Serial3/0/0]ppp authentication-mode chap
[R3-Serial3/0/0]link-protocol ppp
[R3-Serial3/0/0]int s 3/0/1
[R3-Serial3/0/1]ppp authentication-mode chap
[R3-Serial3/0/1]link-protocol ppp
//R2验证
[R2]interface s 3/0/1
[R2-Serial3/0/1]ppp chap user rjw
[R2-Serial3/0/1]ppp chap password cipher 123456
[R2-Serial3/0/1]int s 4/0/0
[R2-Serial4/0/0]ppp chap user rjw
[R2-Serial4/0/0]ppp chap password cipher 123456
