一、实验拓扑

二、实验需求

1.除了R5的环回地址固定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、实验思路

1.IP地址规划
以192.168.1.0/24为基础网段，将其划分为多个网段
2.基础配置
设备命名：将各路由器分别命名为R1-R5。
接口IP配置：根据规划的网段，为各路由器的物理接口配置相应的IP地址。
环回接口配置：为R1-R4分别配置两个环回接口，并分配对应的IP地址，R5配置一个固定环回接口。
3.静态路由配置
为各路由器编写静态路由，使网络内各网段能够相互通信，同时尽量减少每台路由器的路由条目数量，避免出现环路。
对于R1-R4，不直接配置到达R5环回地址5.5.5.0/24的静态路由
4.缺省路由配置
在R1-R4上配置缺省路由
5.避免环路与优化
在R1-R4上分别配置指向自身环回网段的空接口路由，防止路由环路。
6.R4-R5链路配置
为R4到R5的100M链路路由设置更高的优先级（61），使1000M链路正常时作为主用链路，1000M链路故障时自动切换到100M链路.
7.连通性测试
对各路由器之间以及与R5环回地址的连通性进行测试，验证配置的正确性，确保全网可达。

四、实验步骤

1、IP地址的划分

192.168.1.0/24划分5个网段

（1）192.168.1.0000 0000----192.168.1.0/27----骨干链路

192.168.1.0000 0000--192.168.1.0/30---255.255.255.252

192.168.1.0000 0100--192.168.1.4/30

192.168.1.0000 1000--192.168.1.8/30

192.168.1.0000 1100--192.168.1.12/30

192.168.1.0110 0000---192.168.1.96/28

192.168.1.0111 0000--192.168.1.112/28

（5）192.168.1.1000 0000----192.168.1.128/27--R4环回

192.168.1.1000 0000---192.168.1.128/28

192.168.1.1001 0000--192.168.1.144/28
