MGRE综合实验

实验要求：

1.R5为ISP，只能进行地址配置，其所有地址均配为公有地址;
2.     R1和R5间使用PPP的PAP认证，R5为主认证方;
R2与R5之间使用ppp的CHAP认证，R5为主认证方;
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;
4.整个私有网络基本RIP全网可达;
5.所有PC设置私有IP为源IP，可以访问R5环回。

实验思路：

1.配置IP地址；

2.配置缺省路由；

3.配置PAP，CHAP，HDLC封装；

4.配置MGRE，GRE；

5.配置RIP协议；

6.配置NAT，让PC可以访问R5环回。
