RIP环境下的MGRE网络

1.R5为ISP，只能进行IP地址配置；其所有地址均为公有IP地址

[ISP-Serial3/0/0]ip address 15.0.0.2 8
[ISP-Serial3/0/1]ip add 25.0.0.2 8
[ISP-Serial4/0/0]ip add 35.0.0.2 8
[ISP-GigabitEthernet0/0/0]ip add 45.0.0.2 8

2.R1和R5间使用PPP的PAP认证，R5为主认证方；

[r1]ip route-static 0.0.0.0 0 15.0.0.2
[r2]ip route-static 0.0.0.0 0 25.0.0.2
[r3]ip route-static 0.0.0.0 0 35.0.0.2
[r4]ip route-static 0.0.0.0 0 45.0.0.2

[ISP-aaa]local-user huawei password cipher 123456
Info: Add a new user.
[ISP-aaa]local-user huawei service-type ppp

[ISP-Serial3/0/0]ppp authentication-mode pap
[r1-Seria4/0/0]ppp pap local-user huawei password cipher 123456

  R2与R5之间使用PPP的chap认证，R5为主认证方；
[ISP-Serial3/0/1]ppp authentication-mode chap
[r2-Seria4/0/0]ppp chap user huawei
[r2-Seria4/0/0]ppp chap password cipher 123456

  R3与R5之间使用HDLC封装。

3.R1/R2/R3构建一个MGRE环境，R1为中心站点；R1、R4间为点到点的GRE。
