一、拓扑图

二、实验要求

1、R6为isp接口IP 地址均为公有地址；该设备只能配置 IP 地址，之后不能冉对其进行其他任何配置；
2、R1-R5为局域网，私有 IP 地址192.168.1.0/24，请合理分配
3、R1,R2,R4，各有两个环回地址；R5,R6各有一个环回地址；所有路由器上环回均代表连接用户的接口；
4、R3下的两台 PC 通过 DHCP 自动获取 IP 地址；
5、选路最佳，路由表尽量小，避免环路；
6、R1-R5均可以访问R6的环回；
7、R6telnetR5的公有 IP 地址时，实际登陆到R1上；
8、R4与R5正常通过1000n链路，故障时通过100M链路；

三、配置命令

四、测试

1、主机获取DHCP服务的IP 地址

2、R1-R5可以访问R6的环回

3、R6 telnet R5的公有IP地址时,实际登陆到R1上
