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
