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。
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VLAN。
[RouterA] interface eth-trunk 1[RouterA-Eth-Trunk1] portswitch[RouterA-Eth-Trunk1] port link-type trunk[RouterA-Eth-Trunk1] port trunk allow-pass vlan all[RouterA-Eth-Trunk1] quit# 将接口GE1/0/0、GE2/0/0加入到Eth-Trunk 1中。
[RouterA] interface gigabitethernet 1/0/0[RouterA-GigabitEthernet1/0/0] undo shutdown[RouterA-GigabitEthernet1/0/0] eth-trunk 1[RouterA-GigabitEthernet1/0/0] quit[RouterA] interface gigabitethernet 2/0/0[RouterA-GigabitEthernet2/0/0] undo shutdown[RouterA-GigabitEthernet2/0/0] eth-trunk 1[RouterA-GigabitEthernet2/0/0] quit2）配置RouterB# 创建Eth-Trunk接口，并配置允许通过的VLAN。
[RouterB] interface eth-trunk 1[RouterB-Eth-Trunk1] portswitch[RouterB-Eth-Trunk1] port link-type trunk[RouterB-Eth-Trunk1] port trunk allow-pass vlan all[RouterB-Eth-Trunk1] quit# 将接口GE1/0/0、GE2/0/0加入到Eth-Trunk 1中。
[RouterB] interface gigabitethernet 1/0/0[RouterB-GigabitEthernet1/0/0] undo shutdown[RouterB-GigabitEthernet1/0/0] eth-trunk 1[RouterB-GigabitEthernet1/0/0] quit[RouterB] interface gigabitethernet 2/0/0[RouterB-GigabitEthernet2/0/0] undo shutdown[RouterB-GigabitEthernet2/0/0] eth-trunk 1[RouterB-GigabitEthernet2/0/0] quit4、验证配置结果查看Eth-Trunk1的状态，以RouterA为例：<RouterA> display trunkmembership eth-trunk 1Trunk ID: 1used status: VALIDTYPE: ethernetWorking Mode : NormalWorking State: NormalNumber Of Ports in Trunk = 2Number Of UP Ports in Trunk = 2operate status: upInterface Ethernet1/0/0, valid, selected, operate up, weight=1,standby interface NULLInterface Ethernet2/0/0, valid, selected, operate up, weight=1,standby interface NULL用display port vlan命令查看Eth-Trunk端口上可以通过的VLAN信息。

2、配置思路采用如下的思路配置Eth-Trunk：1）创建Eth-Trunk接口并配置IP地址。
2）把以太网接口加入Eth-Trunk接口。
3、配置步骤1）配置RouterA# 创建Eth-Trunk接口，并配置IP地址。
[RouterA] interface eth-trunk 1[RouterA-Eth-Trunk1] ip address 192.168.0.1 255.255.255.0[RouterA-Eth-Trunk1] quit# 将接口GE1/0/0、GE2/0/0加入到Eth-Trunk 1中。
[RouterA] interface gigabitethernet 1/0/0[RouterA-GigabitEthernet1/0/0] undo shutdown[RouterA-GigabitEthernet1/0/0] eth-trunk 1[RouterA-GigabitEthernet1/0/0] quit[RouterA] interface gigabitethernet 2/0/0[RouterA-GigabitEthernet2/0/0] undo shutdown[RouterA-GigabitEthernet2/0/0] eth-trunk 1[RouterA-GigabitEthernet2/0/0] quit2）配置RouterB# 创建Eth-Trunk接口，并配置IP地址。
[RouterB] interface eth-trunk 1[RouterB-Eth-Trunk1] ip address 192.168.0.2 255.255.255.0[RouterB-Eth-Trunk1] quit# 将接口GE1/0/0、GE2/0/0加入到Eth-Trunk 1中。
[RouterB] interface gigabitethernet 1/0/0[RouterB-GigabitEthernet1/0/0] undo shutdown[RouterB-GigabitEthernet1/0/0] eth-trunk 1[RouterB-GigabitEthernet1/0/0] quit[RouterB] interface gigabitethernet 2/0/0[RouterB-GigabitEthernet2/0/0] undo shutdown[RouterB-GigabitEthernet2/0/0] eth-trunk 1[RouterB-GigabitEthernet2/0/0] quit4、检查配置结果在RouterA或RouterB上执行display interface eth-trunk命令，可以看到接口状态为UP。
以RouterA的显示为例。
