在华为设备上配置VRRP MSTP实现网关冗余和负载分担

拓扑如下图所示:

具体配置如下:

SW3:

先创建vlan10、20

vlan batch 10 20

然后在接口下划分trunk、access模式

interface Ethernet0/0/1

port link-type access

port default vlan 10

interface Ethernet0/0/2

port link-type access

port default vlan 20

interface Ethernet0/0/3

port link-type trunk

port trunk allow-pass vlan 10 20

interface Ethernet0/0/4

port link-type trunk

port trunk allow-pass vlan 10 20

配置mstp

stp mode mstp

stp region-configuration

region-name qgtest

instance 10 vlan 10

instance 20 vlan 20

active region-configuration

SW1:

先创建vlan10、20

vlan batch 10 20

配置链路聚合和trunk口

interface Eth-Trunk1

trunkport int g0/0/1

trunkport int g0/0/2

interface Eth-Trunk1

port link-type trunk

port trunk allow-pass vlan 10 20

interface GigabitEthernet0/0/3

port link-type trunk

port trunk allow-pass vlan 10 20

配置mstp

stp mode mstp

stp region-configuration

region-name qgtest

instance 10 vlan 10

instance 20 vlan 20

active region-configuration

stp instance 10 root primary

stp instance 20 root secondary

配置VRRP

interface Vlanif10

ip address 192.168.10.253 255.255.255.0

vrrp vrid 10 virtual-ip 192.168.10.254

vrrp vrid 10 priority 120

interface Vlanif20

ip address 192.168.20.252 255.255.255.0

vrrp vrid 20 virtual-ip 192.168.20.254

vrrp vrid 20 priority 100

SW2:

先创建vlan10、20

vlan batch 10 20

配置链路聚合和trunk口

interface Eth-Trunk1

trunkport int g0/0/1

trunkport int g0/0/2

interface Eth-Trunk1

port link-type trunk

port trunk allow-pass vlan 10 20

interface GigabitEthernet0/0/3

port link-type trunk

port trunk allow-pass vlan 10 20

配置mstp

stp mode mstp

stp region-configuration

region-name qgtest

instance 10 vlan 10

instance 20 vlan 20

active region-configuration

stp instance 20 root primary

stp instance 10 root secondary

配置VRRP

interface Vlanif20

ip address 192.168.20.253 255.255.255.0

vrrp vrid 20 virtual-ip 192.168.20.254

vrrp vrid 20 priority 120

interface Vlanif10

ip address 192.168.10.252 255.255.255.0

vrrp vrid 10 virtual-ip 192.168.10.254

vrrp vrid 10 priority 100

备注:如果SW1有上行接口和上行链路时,其中一个发生故障,VRRP默认是无法感知的,即主备状态无法切换,数据包无法发送出去,这是就要用到track功能。具体配置如下:

SW1/SW2:

vrrp 10 track int g0/0/3 reduced 30

假设G0/0/3为上行口,配置完这条命令之后,即当上行链路发生故障时,其优先级减少30,然后当前优先级小于Backup状态的三层交换机,则主备状态发生切换。
