# 前言 #

*  单臂路由（router-on-a-stick）是指在路由器的一个接口上通过配置逻辑接口的方式，实现原来相互隔离的不同VLAN（虚拟局域网）之间的互联互通

# 一：实验环境 #

### 1.1：软件环境 ###

*  eNSP软件

### 1.2：单臂路由原理 ###

*  在路由器的一个接口上通过配置逻辑接口的方式和E-trunk多链路汇聚，将多条物理链路变为一条E-trunk的逻辑链路，实现原来相互隔离的不同VLAN（虚拟局域网）之间主机的互联互通

### 1.3：华为与思科的单臂路由有区别吗？ ###

*  单臂路由原理本质上相同，只是操作上略有不同
 *  而且，在生产环境中，单臂路由的使用机会很少

### 1.4：实验目的 ###

*  解决单链路负载问题
 *  实现PC1和PC2的互联路通

### 1.4：单臂路由实验拓扑图 ###

### 3.2：总结 ###

涉及链路聚合，交换机需要做trunk的设置

[SW1]int Eth-Trunk1		'//配置Eth-Trunk'
    [SW1-Eth-Trunk1]trunkport GigabitEthernet 0/0/1 to 0/0/2
    [SW1-Eth-Trunk1]port link-type trunk 
    [SW1-Eth-Trunk1]port trunk allow-pass vlan all
    [SW1-Eth-Trunk1]undo shutdown

路由器需要做的trunk设置

[R1]interface Eth-Trunk1		'//配置Eth-Trunk'
    [R1-Eth-Trunk1]trunkport GigabitEthernet 0/0/1 to 0/0/2
    [R1-Eth-Trunk1]q
    [R1]interface Eth-Trunk1.1		'//配置Eth-Trunk子接口'
    [R1-Eth-Trunk1.1]dot1q termination vid 10
    [R1-Eth-Trunk1.1]ip address 192.168.10.1 24
    [R1-Eth-Trunk1.1]arp broadcast enable 	'//开启ARP广播功能'
    [R1-Eth-Trunk1.1]undo shutdown
