ensp——动态路由OSPF实验配置

一
划分网段
先划分两个area的大网段
192.168.1.0000-0000(即192.168.1.0/25)为area0
192.168.1.1000-0000(即192.168.1.128/25)为area1
在area0上继续划分小网段   
192.168.1.0000-0000(即192.168.1.0/27)为R1-R3的链接
192.168.1.0010-0000(即192.168.1.32/27)为R1环回
192.168.1.0100-0000(即192.168.1.64/27)为R2环回
192.168.1.0110-0000(即192.168.1.96/27)为R3环回

二
配置IP
