实验要求
- R5为ISP,只能进行IP地址配置,其所有地址均配为公有IP地址;
- R1和R5间使用PPP的PAP认证,Rs为主认证方;
R1和R5间使用ppp的CHAP认证,Rs为主认证方
R3和R5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。
实验思路
1、配置IP地址
2、私网通,公网通---配置静态路由协议,测试公网通
3、配置R1-R5的ppp的pap认证,R5为主认证方
4、R2与R5之间使用ppp的CHAP认证,R5为主认证方;
5、R3与R5之间使用HDLC封装;
6、配置GRE VPN
7、配置MGRE VPN
(1)配置NHRP协议,构建公共隧道
(2)配置NHRP 协议使分支机构将自己的隧道地址和公网地址发给总部
(3)配置RIPV2,传递两端的私网路由,实现总部和分部,分部和分部之间的互通
(4)在中心站点上开启伪广播功能
(5)关闭中心和分支站点的RIP的水平分割机制
