VRRP（Virtual Router Redundancy Protocol）虚拟路由冗余协议是一种容错协议，用于在网络设备之间提供冗余的网关服务。当主网关发生故障时，备用网关可以迅速接管，确保网络通信的连续性。VLAN负载均衡则通过在多个VLAN之间分配流量，实现网络资源的优化利用。本文将详细介绍如何在华为交换机上配置VRRP和VLAN负载均衡。

VRRP 虚拟冗余链路

两台交换机建立虚拟网关，由VLAN来实现。以下是具体的配置步骤：

配置SWL 1

1. 创建VLAN并配置VLAN接口

   interface vlanif ID
   ip add 192.168.0.253 24
   

2. 配置端口为Trunk类型并允许所有VLAN通过

   Interface g0/0/2
   port link-type trunk
   Port trunk allow-mode vlan all
   

3. 配置VRRP虚拟IP和优先级

   Vrrp vrid 1 vritual-ip 192.168.0.254
   Vrrp vrid 1 priority 120
   

配置SWL2

1. 创建VLAN并配置VLAN接口IP

   ip add 192.168.0.152 24
   

2. 配置端口为Trunk类型并允许所有VLAN通过

   Interface g0/0/1
   Port link-type trunk
   Port trunk allow-mode vlan all
   

3. 配置VRRP虚拟IP和优先级

   Vrrp vrid 1 vritual-ip 192.168.0.254
   Vrrp vrid 1 priority 110
   

配置SWL3

1. 创建VLAN并配置接口

   Interface e0/0/1
   Port link-type access
   Port default vlan id
   Interface e0/0/2
   Port link-type access
   Port default vlan id
   

2. 注意：如果需要删除Trunk端口配置

   undo port trunk allow-mode vlan 2 to 4094
   port trunk allow-mode vlan 1
   undo port link-type

SW1配置（VRRP）

[SW1]interface Vlanif 10
[SW1-Vlanif10]ip address 192.168.1.251 24
[SW1-Vlanif10]vrrp vrid 1 virtual-ip 192.168.1.254
[SW1-Vlanif10]vrrp vrid 1 priority 200
[SW1-Vlanif10]vrrp vrid 1 preempt-mode timer delay 20
[SW1-Vlanif10]vrrp vrid 1 track interface g0/0/1 reduced 100
注意：g0/0/1为出口监控

[SW1]interface Vlanif 20
[SW1-Vlanif20]ip address 192.168.2.251 24
[SW1-Vlanif20]vrrp vrid 1 virtual-ip 192.168.2.254
[SW1-Vlanif20]vrrp vrid 1 priority 150

SW2配置（VRRP）

[SW2]interface Vlanif 10
[SW2-Vlanif10]ip address 192.168.1.252 24
[SW2-Vlanif10]vrrp vrid 1 virtual-ip 192.168.1.254
[SW2-Vlanif10]vrrp vrid 1 priority 150

[SW2]interface Vlanif 20
[SW2-Vlanif20]ip address 192.168.2.252 24
[SW2-Vlanif20]vrrp vrid 1 virtual-ip 192.168.2.254
[SW2-Vlanif20]vrrp vrid 1 priority 200
[SW2-Vlanif20]vrrp vrid 1 track interface g0/0/2 reduced 100
注意：g0/0/2为出口监控
[SW2-Vlanif20]vrrp vrid 1 preempt-mode timer delay 20
