# 华为交换机Trunk配置 #

**Trunk**  
采用Trunk中继链路技术可以实现不同交换机同网段的Vlan间通信。Trunk中继技术可以实现在一条物理线路中可以传递多个Vlan间的信息，如：交换机从属于Vlan2的端口接收到数据，在Trunk中继链路上进行传输前，会先打上一个标记，表明该数据包是Vlan2的，到达对方交换机时，交换机会将该标记去掉，只发送到属于Vlan2的端口上。

例：以下拓扑图中，子网掩码都为255.255.255.0  
Vlan1：  
左：192.168.1.1 192.168.1.2  
右：192.168.1.3 192.168.1.4  
Vlan2：  
左：192.168.:2.1 192.168.2.2  
右：192.168.2.3 192.168.2.4  
Vlan3：  
左：192.168.3.1 192.168.3.2  
右：192.168.3.3 192.168.3.4

不同交换机同网段Vlan之间能够互相ping通，说明两个交换机接口配置的Trunk中继链路技术实现成功。
