MGRE实验

要求：

• R5为ISP，只能进行IP地址配置；其所有的IP地址均为公有IP地址

• R1和R5之间使用PPP的PAP认证，R5为主认证方

R2和R5之间使用PPP的chap认证，R5为主认证方

R3和R5之间使用HDLC封装

• R1/R2/R3构建一个MGRE环境，R1为HUB；

R1/R4之间构建一个GRE环境

• 整个私有网络基于RIP全网可达

• 所有PC设置私有IP为源IP，可以访问R5环回

[ISP-aaa]local-user admin service-type ppp

[ISP-Serial1/0/0]ppp authentication-mode pap

[r1-Serial1/0/0]ppp pap local-user admin password cipher 123456

重启接口

chap认证

[ISP]aaa

[ISP-aaa]local-user huawei password cipher 654321

[ISP-aaa]local-user huawei service-type ppp

[ISP-Serial2/0/0]ppp authentication-mode chap

[r2-Serial2/0/0]ppp chap user huawei

[r2-Serial2/0/0]ppp chap password cipher 654321
