1、二层和三层Eth-Trunk接口配置实例配置实例文章出处：原创路由器可以对多个以太网接口捆绑形成一个Eth-Trunk逻辑接口，Eth-Trunk接口的主 要目的是增大带宽和提高设备之间链路的可靠性。Eth-Trunk接口可以工作在二层模式或三 层模式。二层模式的Eth-Trunk接口类似交互机的接口，只负责二层数据包的转发；三层模 式的Eth-Trunk接口则类似路由器的接口，可以配上IP地址实现路由功能。本文为大家介 绍如何在华为的路由器里配置二层和三层Eth-Trunk接口。一、二层Eth-Trunk接口配置实例1、组网结构和需求如下图所示， RouterA 和 RouterB 之间通过
2、 Eth-Trunk1 连接， Eth-Trunk1 是二层端口。 将 Eth-Trunk1 配置为 Trunk 类型接口，允许 RouterA 和 RouterB 之间的所有 VLAN 帧通过。2、配置思路采用如下的思路配置二层Eth-Trunk端口允许VLAN通过：1）创建 Eth-Trunk 接口。2）将Eth-Trunk接口转为二层端口。3 ）将Eth-Trunk端口配置为Trunk类型的端口，并允许所有VLAN帧通过。4）将成员口接入 Eth-Trunk 端口中。3、配置步骤1 ）配置 RouterA#创建Eth-Trunk接口，并配置允许通过的VLANRouterA interfa
