静态路由的配置实验_路由器静态路由的配置实验内容

一、实验拓扑

二、实验需求

1.除了R5的环回地址固定在5.5.5.0/24，其他网段基于192.168.1.0/24进行合理划分
2.R1-R4每个路由器存在两个环回接口，模拟PC，地址也在192.168.1.0/24网络内
3.R1-R4不能直接编写到达5.5.5.0/24的静态路由，但依然可以访问
4.全网可达，尽量减少每台路由器的路由条目数量，避免环路
5.R4与R5间，正常1000M链路通信，故障时自动改为100M

三、实验步骤

1、划分网段

可以将192.168.1.0/24网段划分为骨干网段，以及R1到R4的环回网段
划分结果为：192.168.1.0/24

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

2：192.168.1.32/27 R1
192.168.1.32/28
192.168.1.48/28

3：192.168.1.64/27 R2
192.168.1.64/28
