链路聚合ET-TRUNK配置实例

1、路由器配置实例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Eth-Trunk1连接，Eth-Trunk1是二层端口
