OSPF综合实验

一、IP地址的划分

172.16.0.0/16

划分为8个网段，每个区域分配一个网段，所以子网掩码向后掩3位。

1)  172.16.0.1 -- 172.16.31.254
2)  172.16.32.1 -- 172.16.63.254
3)  172.16.64.1 -- 172.16.95.254
4)  172.16.96.1 -- 172.16.127.254
5)  172.16.128.1 -- 172.16.159.254
6)  172.16.160.1 -- 172.16.191.254
7)  172.16.192.1 -- 172.16.223.254
8)  172.16.224.1 -- 172.16.255.254
 

网段的分配

area0: 172.16.0.0/19

area1: 172.16.32.0/19

area2: 172.16.64.0/19

area3: 172.16.96.0/19

area4: 172.16.128.0/19
