1. 需求

IP地址规划：完整详细IP地址方案。
vlan的规划：至少三个VLan，并且分配到不同的交换机上。配置VLAN，且完成相同vlan不同vlan之间的通信
路由规划：规划合适路由保证全网能够互访。
交换机之间为了防止冗余链路形成环路，配置生成树
配置DHCP服务器，使所有主机部门一内所有主机能自动获取IP地址
DNS服务器的配置：所有主机能使用DNS服务器，并配置Web服务器地址域名为www.baidu.com,确保企业内所有主机能访问成功。
Web服务器的配置：静态内容：学号+姓名+年级+网络工程实验。
FTP服务器的配置：确保企业内所有主机能访问。
附加一：只有部门一能访问FTP。
附加二：内网地址转换一次后访问外网。
