使用ensp进行ppp协议综合实验

实验拓扑

实验划分

AR1的Serial3/0/0接口：192.168.1.1/24；

AR2的Serial3/0/0接口：192.168.1.2/24；

AR2的Serial3/0/1和4/0/0的聚合接口：192.168.2.2/24；

AR3的Serial3/0/0和3/0/1的聚合接口：192.168.2.3/24；

实验需求

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

实验结果

(1)、增加接口

设置里面下滑找到2SA添加接口

注意链接的线也需要使用Serial

(2)、配置接口IP并MP聚合R2和R3之间的链路

R1:

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

R2:

[R2]int s 3/0/0	
[R2-Serial3/0/0]ip address 192.168.1.2 24
[R2]inter Mp-group 0/0/0
[R2-Mp-group0/0/0]ip ad 192.168.2.2 24
[R2-Mp-group0/0/0]q
[R2]inter ser3/0/1
[R2-Serial3/0/1]ppp mp Mp-group 0/0/0
[R2-Serial3/0/1]inter s4/0/0
[R2-Serial4/0/0]ppp mp Mp-group 0/0/0

R3:

[R3]inter Mp-group 0/0/0	
[R3-Mp-group0/0/0]ip address 192.168.2.3 24
[R3]inter s3/0/0
[R3-Serial3/0/0]ppp mp Mp-group 0/0/0
[R3-Serial3/0/0]inter s3/0/1
[R3-Serial3/0/1]ppp mp Mp-group 0/0/0

(3)、单向chap验证

R2做主验证方，R1做被验证方

R2:

[R2]aaa
[R2-aaa]local-user dumj password cipher 123456
[R2-aaa]local-user dumj service-type ppp
[R2]inter s3/0/0
[R2-Serial3/0/0]ppp authentication-mode chap

R1:

[R1]int s3/0/0
[R1-Serial3/0/0]ppp chap user dumj
[R1-Serial3/0/0]ppp chap password cipher 123456

验证：可以ping通，且接口双up

(4)、双向chap验证

R2做主验证方，R3做被验证方

R2:

[R2]aaa
[R2-aaa]local-user dumj password cipher 123456
[R2-aaa]local-user dumj service-type ppp
[R2]inter s3/0/1
[R2-Serial3/0/1]ppp authentication-mode chap
[R2-Serial3/0/1]int s4/0/0
[R2-Serial4/0/0]ppp authentication-mode chap

R3:

[R3]int s3/0/0
[R3-Serial3/0/0]ppp chap user dumj
[R3-Serial3/0/0]ppp chap password cipher 123456
[R3-Serial3/0/0]int s3/0/1
[R3-Serial3/0/1]ppp chap user dumj
[R3-Serial3/0/1]ppp chap password cipher 123456

R3做主验证方，R2做被验证方

R3:

[R3]aaa
[R3-aaa]local-user dumj password cipher 123456
[R3-aaa]local-user dumj service-type ppp
[R3]int s3/0/0
[R3-Serial3/0/0]ppp authentication-mode chap
[R3-Serial3/0/0]int s3/0/1
[R3-Serial3/0/1]ppp authentication-mode chap

R2:

[R2]int s3/0/1
[R2-Serial3/0/1]ppp chap user dumj
[R2-Serial3/0/1]ppp chap password cipher 123456
[R2-Serial3/0/1]inter s4/0/0
[R2-Serial4/0/0]ppp chap user dumj
[R2-Serial4/0/0]ppp chap password cipher 123456
