OSPF综合实验

实验拓补

实验步骤

分配IP

R1-R8的建邻环回用X.X.X.X/32表示

按编号来即可

As间的骨干链路IP地址

172.16.1.0/16

借8为到172.16.1.0/24

这5个路由器的业务网段我们使用：

R3:172.16.3.0/24

R4:172.16.4.0/24

R5:172.16..5.0/24

R6:172.16.6.0/24

R7:172.16.7.0/24

将172.16.1.0/24拉到27分6个子网段出来

172.16.1.0/27

172.16.1.4/27

172.16.1.8/27

172.16.1.12/27

172.16.1.16/27

172.16.1.20/27

再往后拉3位让掩码到30

172.16.1.0/30

172.16.1.4/30

172.16.1.8/30

172.16.1.12/30

172.16.1.16/30

172.16.1.20/30
