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1000M链路，故障时通过100m链路;

第一步

首先我们按照要求进行子网划分

192.168.1.0/27（主网段）
192.168.1.32/27（R1环回）
192.168.1.64/27（R1环回）
192.168.1.96/27（R2环回）
192.168.1.128/27（R2环回）
192.168.1.160/27（R4环回）
192.168.1.192/27（R4环回）
192.168.1.224/27（用于R3的DHCP配置）
其中192.168.1.0/27作为主网段，而子网段需要7个网段，对其进行子网划分:
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
192.168.1.24/30（保留）
192.168.1.28/30（保留）
如下图所示
