HCIP-VLAN-hybrid接口+DHCP实验

1.拓扑及实验需求

2.需求分析

需要用到的技术

1、虚拟局域网（VLAN）

2、动态主机配置协议（DHCP）

3、单臂路由

首先先完成交换部分，创建对应的vlan将PC1与PC3划入vlan2且接口类型为access，而以外的PC都划入如拓扑图对应vlan并且接口类型为hybrid，hybrid接口的配置规划如下图的拓扑注释，各交换机间的链路接口类型为trunk且放通所有创建的vlan，LSW1与路由器连接的链路接口类型为hybrid接口且T列表只放通vlan2，U列表则放通vlan3456；然后配置路由部分，配置单臂路由，配置DHCP地址池等

以下为规划后的拓扑注释图

3.详细配置
