PPP实验

一.实验思路

1.对接口进行配置IP
2.将R2上面的两个serial接口与R3的两个接口进行链路聚合，然后配置IP
3.在R2（验证方）上配置PPP chap协议
4.在R1上配置验证用户名
5.要使R3和R2能进行双向chap验证，要在R3上配置ppp chap协议
6.在R2上配置验证用户名
7.每一项chap完成后进行ping测试，看是否成功！

二.实验步骤

1.给R1接口配置IP[R1]int s 3/0/0[R1-Serial3/0/0]ip address 192.168.1.1 242.给R2的一个接口配置IP[R2]int s 3/0/0[R2-Serial3/0/0]ip address 192.168.1.2 24

3.链路聚合
R2:[R2]int Mp-group 0/0/0    ----  创建mp-group接口[R2]int Serial 3/0/1      ----  进入3/0/1物理接口，将该接口划分到聚合接口中    [R2-Serial3/0/1]ppp mp Mp-group 0/0/0[R2]int s 4/0/0           ----  进入4/0/0物理接口，将该接口划分到聚合接接口  [R2-Serial4/0/0]ppp mp Mp-group 0/0/0

R3:[R3]int Mp-group 0/0/0  [R3]int s 3/0/0[R3-Serial3/0/0]ppp mp Mp-group 0/0/0[R3]int s 3/0/1 [R3-Serial3/0/1]ppp mp Mp-group 0/0/0

4.聚合之后，给两个聚合接口配置IP[R2]int Mp-group 0/0/0[R2-Mp-group0/0/0]ip address 192.168.2.1 24
[R3]int Mp-group 0/0/0  [R3-Mp-group0/0/0]ip address 192.168.2.2 24

5.给R2配置ppp chap协议[R2]aaa[R2-aaa]local-user xjf password cipher xjf123456Info: Add a new user.[R2-aaa]local-user xjf service-type ppp[R2-aaa]q[R2]int serial 3/0/0[R2-Serial3/0/0]ppp authentication-mode chap
被验证方：[R1]int s 3/0/0[R1-Serial3/0/0]ppp chap user xjf[R1-Serial3/0/0]ppp chap password cipher xjf123456进行测试一下：

6.让R2与R3进行双向chap验证！

A.先让R2是验证方，R3是被验证方：[R2]aaa[R2-aaa]local-user zhangsan password cipher zs123456  --- 创建张三用户和密码Info: Add a new user.[R2-aaa]local-user zhangsan service-type ppp   ----  设置服务类型[R2]int Serial 3/0/1[R2-Serial3/0/1]ppp authentication-mode chap   ---  给物理接口设置验证方式[R2-Serial3/0/1]q[R2]int s 4/0/0[R2-Serial4/0/0]ppp authentication-mode chap   ---  给物理接口设置验证方式被验证方：[R3-Serial3/0/0]ppp chap user zhangsan[R3-Serial3/0/0]ppp chap password cipher zs123456[R3-Serial3/0/0]q[R3]int s 3/0/1[R3-Serial3/0/1]ppp chap user zhangsan[R3-Serial3/0/1]ppp chap password cipher zs123456


B.让R3是验证方，R2是被验证方：[R3]aaa[R3-aaa]local-user lisi password cipher ls123456  --- 创建李四用户和密码[R3-aaa]local-user lisi service-type ppp       ---- 设置服务类型[R3-aaa]q[R3]int s 3/0/0[R3-Serial3/0/0]ppp authentication-mode chap      --- 给物理接口设置验证方式[R3-Serial3/0/0]q[R3]int s 3/0/1[R3-Serial3/0/1]ppp authentication-mode chap    --- 给物理接口设置验证方式

被验证方：[R2]int s 3/0/1[R2-Serial3/0/1]ppp chap user lisi [R2-Serial3/0/1]ppp chap password cipher ls123456[R2-Serial3/0/1]q[R2]int s 4/0/0[R2-Serial4/0/0]ppp chap user lisi[R2-Serial4/0/0]ppp chap password cipher ls123456进行测试一下：
