HCIP（DSVPN）实验

一，实验要求：

1、r5为isp，只能进行ip地址的配置，其所有ip地址均为共有ip地址
2、r1和r5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
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
4、整个私有网络基于rip全网可达
5、所有pc设置私有ip为源ip，可以访问r5环回

二，拓扑图

三，需求分析

给各个路由器配置地址。配置缺省路由。开启R1/R5间PPP的CHAP协议。对R3/R4/R5进行HDLC封装。R1/R2/R3构造mgre环境。配置R1/R4之间GRE。
