IP第三次作业

实验拓扑及要求如图所示: 

我连接的拓扑:

实验思路：

1.按图示配置设备IP地址

2.使用路由协议让私网公网全网通

3.配置pap，chap，HDLC封装

4.配置MGRE，GRE

5.配置RIP协议

6.配置NAT，使得访问内网环回

 实验开始：

电脑如图配置即可(我用的PC1):

2.内网外网通:
实现外网通：
题目说R5(我图的R2）只能进行
Ip配置，在其他几个路由上配置一个缺省即可：
R1：[R1]ip route-static 0.0.0.0 0 15.1.1.2
R3：[R3]ip route-static 0.0.0.0 0 45.1.1.1
R4：[R4]ip route-static 0.0.0.0 0 35.1.1.1
R5：[R5]ip route-static 0.0.0.0 0 25.1.1.1

R1和R2间使用PPP的PAP认证，R2为主认证方
