网络分类简述与数据链路层协议

网络分类简述与数据链路层协议

• 实验拓扑
• 

• 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

• 实验思路

1. 给R1和R2的s3/0/0接口配置IP地址，网段192.168.1.0/24
2. R2---主验证方，R1----被验证方，配置PPP协议。R2开启PPP协议，设置用户wqq，密码：123123，进入s3/0/0接口开启PPP协议，R1的s3/0/0接口配置PPP协议
3. R2、R3链路聚合，创建MP-Group组，创建IP地址将接口加入MP-Group组
4. R2---主验证方，R3----被验证方，配置PPP协议。
5. R3---主验证方，R2----被验证方，配置PPP协议。

• 实验步骤

1. 配置IP地址

[R1]int s3/0/0

[R1-Serial3/0/0]ip add 192.168.1.1 24

[R1-Serial3/0/0]

[R2]int s3/0/0

[R2-Serial3/0/0]ip add 192.168.1.2 24

1. 配置R2对R1的PPP

R2：

[R2]aaa

[R2-aaa]local-user wqq password cipher 123123

Info: Add a new user.

[R2-aaa]lo

[R2-aaa]local-user wqq se

[R2-aaa]local-user wqq service-type ppp

[R2-aaa]int s3/0/0

[R2-Serial3/0/0]ppp au

[R2-Serial3/0/0]ppp authentication-mode chap

[R2-Serial3/0/0]link-

[R2-Serial3/0/0]link-protocol ppp

R1：

[R1]int s3/0/0

[R1-Serial3/0/0]ppp chap user wqq

[R1-Serial3/0/0]ppp chap password cipher 123123

[R1-Serial3/0/0]

测试：

1. R2与R3链路聚合，创建MP-Group组，创建IP地址将接口加入MP-Group组

在R2上创建组并配置IP地中，将R2两个接口加入组中

[R2]int MP-Group 0/0/0

[R2-Mp-group0/0/0]ip add 192.168.2.2 24

[R2-Mp-group0/0/0]int s3/0/1

[R2-Serial3/0/1]ppp mp MP-Group 0/0/0

[R2-Serial3/0/1]int s4/0/0

[R2-Serial4/0/0]ppp mp MP-Group 0/0/0

在R2上创建组并配置IP地中，将R2两个接口加入组中

[R3]int MP-Group 0/0/0

[R3-Mp-group0/0/0]ip add 192.168.2.3 24

[R3-Mp-group0/0/0]int s3/0/0

[R3-Serial3/0/0]ppp mp MP-Group 0/0/0

[R3-Serial3/0/0]int s3/0/1

[R3-Serial3/0/1]ppp mp MP-Group 0/0/0

1. R2---主验证方，R3----被验证方，配置PPP协议。

[R2]aaa

[R2-aaa]local-user wqq password cipher 123123

[R2-aaa]local-user wqq se

[R2-aaa]local-user wqq service-type ppp

[R2-aaa]int s3/0/1

[R2-Serial3/0/1]ppp au

[R2-Serial3/0/1]ppp authentication-mode chap

[R2-Serial3/0/1]link-

[R2-Serial3/0/1]link-protocol ppp

[R2-Serial3/0/1]int s4/0/0

[R2-Serial4/0/0]ppp authentication-mode chap

[R2-Serial4/0/0]link-protocol ppp

[R3]int s3/0/0

[R3-Serial3/0/0]ppp chap user wqq

[R3-Serial3/0/0]ppp chap password cipher 123123

[R3-Serial3/0/0]int s3/0/1

[R3-Serial3/0/1]ppp chap user wqq

[R3-Serial3/0/1]ppp chap password cipher ******

测试：

5、R3---主验证方，R2----被验证方，配置PPP协议。

[R3]aaa

[R3-aaa]local-user wqq password cipher 123123

Info: Add a new user.

[R3-aaa]local-user wqq se

[R3-aaa]local-user wqq service-type ppp

[R3-aaa]int s3/0/0

[R3-Serial3/0/0]ppp au

[R3-Serial3/0/0]ppp authentication-mode chap

[R3-Serial3/0/0]link-

[R3-Serial3/0/0]link-protocol ppp

[R3-Serial3/0/0]int s3/0/1

[R3-Serial3/0/1]ppp authentication-mode chap

[R3-Serial3/0/1]link-protocol ppp

[R2]int s3/0/1

[R2-Serial3/0/1]ppp chap user wqq

[R2-Serial3/0/1]ppp chap password cipher 123123

[R2-Serial3/0/1]int s4/0/0

[R2-Serial4/0/0]ppp chap user wqq
