实际操作图

 

 1，IP划分分配

---

[r1]interface Serial 4/0/0

[r1-Serial4/0/0]ip add 192.168.1.1 24

[r2]interface Serial 4/0/0

[r2-Serial4/0/0]ip address 192.168.1.2 24

 

[r2]int Mp-group 0/0/0

[r2-Mp-group0/0/0]ip add 192.168.2.1 24

[r3]int Mp-group 0/0/0

[r3-Mp-group0/0/0]ip address 192.168.2.2 24

pp中mp使物理口合并IP划分给逻辑口上

2单项验证chap

[r2]aaa

[r2-aaa]local-user wangdaye password cipher wdy12345

Info: Add a new user.

[r2-aaa]local-user wangdaye service-type ppp

[r2]interface Serial 4/0/0

[r2-Serial4/0/0]ppp authentication-mode chap

 

[r1]interface Serial 4/0/0

[r1-Serial4/0/0]ppp chap user wangdaye

[r1-Serial4/0/0]ppp chap password cipher wdy12345

 

 3双向验证chap
