背景：学校有1个办公室，10个教室。每个教室一个摄像头，一个AP，40台电脑。电信接入点为光猫、ip地址为自动获取。

要求：
1、办公室、教室、wifi、监控网络可以实现二层数据隔离。
2、办公室、wifi可以连接互联网，wifi不允许与其它部门互通。
3、教室、监控网络默认不允许连接互联网网。需要的时候可以单独控制连接互联网。
4、画出网络拓扑图，列出设备清单。
5、在模拟器中配置好设备，完成以上要求。
6、在真实设备上面完成配置。

本实验注意事项：

1、中心交换机必须把所有的vlan都添加进去，否则各vlan无法通过中心交换机连接路由器。

2、R1路由器上使用dhcp服务器给各终端设备分配ip地址时，除了在相应端口上做配置外还要在全局打开dhcp enable。

3、如果DCHP Server需要排除某个IP地址，必须在该IP没有被使用的前提下进行。

4、如果在R1使用静态缺省路由，必须把下一跳指向运营商的IP（网关），不能只指向相应的接口。

5、子接口间的数据过滤必须在子接口的outboad方向应用ACL，否则终端设备无法ping通其网关。
