HCIA实验

实验目的：

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，之后不能再对其进行任何配置；
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IP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下面的两台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、R6 telnet R5的公有地址时，实际登录到R1上；
8、R4与R5正常通过1000M链路，故障时通过100m链路；

实验步骤：

1.子网划分：

192.168.1.0 30

192.168.1.4 30

192.168.1.8 30

192.168.1.12 30

192.168.1.16 30

192.168.1.20 30
