这里只单纯配置了VRRP

创建两个vlan 10 20，做负载分担

华为VRRP配置（虚拟网关备份协议）_华为

两台是设备Eth-trunk1口放行vlan10 20

SW1配置

[sw1]vlan batch 10 20
[sw1]interface vlan10
[sw1-Vlanif10]ip ad 192.168.10.1 24　　#配置物理网关地址
[sw1-Vlanif10]vrrp vrid 1 virtual-ip 192.168.10.254　　#配置vrrp组1  配置虚拟网关地址
[sw1-Vlanif10]vrrp vrid 1 priority 120　　#配置优先级为120，默认100数字越大越优先，使它成为vlan10的Master
[sw1-Vlanif10]vrrp vrid 1 track interface GigabitEthernet0/0/3 reduced 30　　#检测上联端口，如果断开优先级降低30（之后会作为backup）

[sw1-Vlanif10]dis this
#
interface Vlanif10
 ip address 192.168.10.1 255.255.255.0
 vrrp vrid 1 virtual-ip 192.168.10.254
 vrrp vrid 1 priority 120
 vrrp vrid 1 track interface GigabitEthernet0/0/3 reduced 30
#

[sw1-Vlanif20]ip address 192.168.20.1 255.255.255.0　　#配置vlan20的物理网关
[sw1-Vlanif20]vrrp vrid 2 virtual-ip 192.168.20.254　　#配置vlan20的虚拟网关
[sw1-Vlanif20]vrrp vrid 2 preempt-mode timer delay 20　　#延迟20秒后抢占
[sw1-Vlanif20]dis this
#
interface Vlanif20
 ip address 192.168.20.1 255.255.255.0
 vrrp vrid 2 virtual-ip 192.168.20.254
 vrrp vrid 2 preempt-mode timer delay 20
#

SW2配置

[sw2]vlan batch 10 20
[sw2-Vlanif10]dis this
#
interface Vlanif10
 ip address 192.168.10.2 255.255.255.0　　#配置vlan10网关
 vrrp vrid 1 virtual-ip 192.168.10.254　　#配置vrrp组1 配置虚拟网关和SW1一样
 vrrp vrid 1 preempt-mode timer delay 20　　#延迟20s后抢占
#

[sw2-Vlanif20]dis this
#
interface Vlanif20
 ip address 192.168.20.2 255.255.255.0　　#配置vlan20网关
 vrrp vrid 2 virtual-ip 192.168.20.254　　#配置vrrp组2 配置虚拟网关和SW1一样
 vrrp vrid 2 priority 120　　#配置优先级为120，使vrrp2 成为vlan20的Master

 vrrp vrid 2 track interface GigabitEthernet0/0/22 reduced 30  #配置上联链路检测，如果断开优先级减去30 使它成为backup
