- 基于CEF的MLS
- 链路聚合
三层交换技术
三层交换机使用三层交换技术实现vlan间通信，二层交换加三层转发的功能
特点：一次路由，多次交换
传统的MLS（多层交换）
①从三层引擎中获悉二层重写信息在硬件中创建一个MLS条目
②负责重写和转发数据流中的后续数据包
基于CEF的MLS
①转发信息库（FIB）：相当于路由表的功能
②邻接关系表：能看到邻端的MAC地址
三层交换机具有路由功能和高速转发数据包
链路聚合
链路聚合有两种
①手工负载分担
该模式下所有接口都参与数据的转发，平均分担流量；
如果某条链路故障，链路聚合组会自动在剩余的活动链路中平均分担流量；
当需要在两个直连设备间提供一个较大的带宽而设备不支持LACP协议时。
②静态LACP
需手工创建以太trunk口，手工加入以太trunk成员接口，由LACP协商确定活动接口和非活动接口；
M:N模式m条链路处于活动状态，n条处于非活动状态，当m条链路中有条链路出现故障，会从n条备份链路选择优先级最高的接替故障链路，并从非活跃状态变为活跃状态开始转发数据。
实验：
首先将主机IP地址配好，然后将主机分别划分到相应vlan中
