项目5-1：配置VLAN间路由（三层交换）

拓扑：

Cisco CCNA 之 Packet Tracer 练习题系列

项目说明：

假设核心交换机名称为：COM；分支交换机分别为：PAR1、PAR2、PAR3，分别通过Port 1的光线模块与核心交换机相连；并且假设VLAN名称分别为COUNTER、MARKET、MANAGING……

端口分配（交换机 PAR1、PAR2和 PAR3）

项目目标

1、对交换机进行基本配置（密码为cisco）

2、设置VTP（核心、分支交换机上都设置 密码cisco 域名 czie）
3、配置中继（核心、分支交换机上都设置）
4、创建VLAN（在server上设置）
5、将交换机端口划入VLAN
6、配置三层交换使不同网段能相互ping通
