单臂路由 有缺陷 三层交换机
1.创建vlan 原则：所有交换机创建一模一样的vlan
2.把接口类型做好 原则：只在交换机的接口配置，交换机之间一定是trunk,交换机与 其他设备一定是aceess（单臂路由和无线设备除外）
3.做MSTP 原则：所有MSTP配置必须一模一样（优先级的命令除外）
4.网关
5.路由
6.DHCP 全局：网关和DHCP服务器是同一台设备
网关处开全局模式，创建地址池
接口：几乎不用
中继：网关和DHCP服务器不是同一台设备且不是同一个网段
中继：网关在哪里，哪里做中继命令（2条命令）
服务器：服务器IP地指处开全局，创建地址池
租约： 50% 发的是单播 默认3天，剩余1.5，发一个更新租约 的request报文，续约后变为1.5+3=4.5
87.5% 发的广播，发给网络中的所有DHCP服务器一个光 的request报文
