华为企业组网实例：VRRP+MSTP典型组网配置

VRRP+MSTP典型组网配置

VRRP是一种容错协议，它保证当主机的下一跳路由器出现故障时，由另一台路由器来代替出现故障的路由器进行工作，从而保持网络通信的连续性和可靠性。

MSTP：多生成树协议，通过生成多个生成树，来解决以太网环路问题。

实验拓扑

一、VLAN配置

SW3配置

sy sw3
un in en
vlan batch 10 20 30 40

interface g0/0/2
 port link-type access
 port default vlan 10
 q
interface g0/0/3
 port link-type access
 port default vlan 20

SW4配置

sy sw4
un in en
vlan batch 10 20 30 40
interface g0/0/2
 port link-type access
 port default vlan 30

二、Trunk配置

SW3配置

interface g0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10 20
 
interface g0/0/4
 port link-type trunk
 port trunk allow-pass vlan 10 20

SW1配置

sy sw1
un in en
vlan batch 10 20 30 40

interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10 20
 
interface GigabitEthernet0/0/3

SW2配置

sy sw2
un in en
vlan batch 10 20 30 40

interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 30 40
 
interface GigabitEthernet0/0/3

三、链路聚合

SW1和SW2之间我们用两根网线，做成链路聚合。

SW1配置

[hxsw1]int Eth-Trunk 1
[hxsw1-Eth-Trunk1]mode lacp-static
[hxsw1-Eth-Trunk1]trunkport g0/0/2
Info: This operation may take a few seconds. Please wait for a moment...done.
[hxsw1-Eth-Trunk1]trunkport g0/0/5
Info: This operation may take a few seconds. Please wait for a moment...done.
