華為VRRP配置（虛擬網關備份協議）

這里只單純配置了VRRP

創建兩個vlan 10 20，做負載分擔

 

 

兩台是設備Eth-trunk1口放行vlan10 20

SW1配置

[sw1]vlan batch 10 20    #創建vlan10 20

[sw1-Vlanif10]dis this
#
interface Vlanif10
 ip address 192.168.10.1 255.255.255.0 #配置物理網關地址
 vrrp vrid 1 virtual-ip 192.168.10.254 #配置vrrp組1 配置虛擬網關地址
 vrrp vrid 1 priority 120 #配置優先級為120，默認100數字越大越優先，使它成為vlan10的Master
 vrrp vrid 1 track interface GigabitEthernet0/0/3 reduced 30 #檢測上聯端口，如果斷開優先級降低30（之后會作為backup）
#
　　
[sw1-Vlanif20]dis this
#
interface Vlanif20
 ip address 192.168.20.1 255.255.255.0 #配置vlan20的物理網關
 vrrp vrid 2 virtual-ip 192.168.20.254 #配置vlan20的虛擬網關
 vrrp vrid 2 preempt-mode timer delay 20 #延遲20秒后搶占        
#

 

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網關
 vrrp vrid 1 virtual-ip 192.168.10.254　　#配置vrrp組1 配置虛擬網關和SW1一樣
 vrrp vrid 1 preempt-mode timer delay 20　　#延遲20s后搶占
#

[sw2-Vlanif20]dis this
#
interface Vlanif20
 ip address 192.168.20.2 255.255.255.0　　#配置vlan20網關
 vrrp vrid 2 virtual-ip 192.168.20.254　　#配置vrrp組2 配置虛擬網關和SW1一樣
 vrrp vrid 2 priority 120　　#配置優先級為120，使vrrp2 成為vlan20的Master

 vrrp vrid 2 track interface GigabitEthernet0/0/22 reduced 30  #配置上聯鏈路檢測，如果斷開優先級減去30 使它成為backup

這樣可實現負載分擔，vlan10的流量走SW1，vlan20的流量走SW2
