VLAN实验

1.实验拓扑如下：

2.实验要求：

将PC1、PC2、PC6划分到VLAN2,其他三个主机划分到VLAN3。

R1路由器使用DHCP在192.168.1.1/24网段分配地址给每台主机，并且PC1可以Ping通PC6。.

3.实验配置思路：

先在两台交换机上创建VLAN2和3，再将主机与交换机相连的端口划分到对应的VLAN中，再对干道进行切换到trunk模式，再在交换机连接路由器的端口上进行逻辑（虚拟）上分子接口配置对应IP地址。最后进行子接口的arp与dhcp协议的激活。对路由器进行DHCP配置。

5.测试：

查看各个主机的IP地址，再看PC1、PC2、PC5是否在一个网段，再用PC1ping通PC6。

 

 

 

 6.实验总结：这次实验让我对VLAN的创建与划分还有中继干道的定义与路由器子接口的划分有了更清晰的了解，同时也让我注意到了一些小问题，比如路由器子接口的协议都需要手动激活，而原本的物理接口是不需要收到激活的。也对DHCP进行了回顾。
