MGRE综合实验报告-优快云博客

一、实验拓扑
二、实验要求
1.R5为ISP，只能进行IP地址配置，其所有地址均配为公有I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.R1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。
三、实验思路
1.按图示内容进行IP地址配置
2.公网通
3.认证
4.构建MGRE环境，GRE
5.RIP全网可达
6.NAT配置

四、实验步骤
1.PC端手动配置地址(R1为例)
