HCIP第一天作业

一、划分IP地址
将192.168.1.0/24划分为六个网段，分别为：
192.168.1.0/27
192.168.1.32/27
192.168.1.64/27
192.168.1.96/27
192.168.1.128/27
192.168.1.160/27
其中将192.168.1.0/27划分六个网段，分别为：
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

R1环回：
将192.168.1.32/27划分为：
192.168.1.32/28 192.168.1.48/28

同理，R2环回：
192.168.1.64/28 192.168.1.80/28

R4环回：
192.168.1.128/28 192.168.1.144/28
二、静态路由配置：
