1、 实验目的
通过本实验可以：
- 理解二层交换的基本原理
- 掌握交换机的基本配置
- 掌握交换机VLAN划分
- 掌握实现不同局域网的通信
- 掌握VRRP以及链路捆绑
- 掌握DHCP的基本配置
2、 拓扑结构
3、 实验需求
-
参照逻辑拓扑，使用合适的线缆完成物理拓扑的搭建
-
完成相应配置，PC1与PC3在一个局域网里，PC2与PC4在一个局域网里，并捆绑三层交换机之间的端口
-
在R1上完成相应配置，并启用动态地址池，实现各个主机可以获取到地址并且能够相互通信
-
开启虚拟网关冗余协议，R1作为PC1与PC3局域网的主路由器，R2作为PC2与PC4局域网的主路由器
-
合理划分R1,R2,R3之间的地址，全网启用路由协议，实现主机与R3之间的通信
-
分析此时PC2能否获取到动态地址，并进行检验
-
关闭R2的Master接口，观察日志信息，分析此时网络环境是否正常
