本文档详细介绍了如何配置MSTP生成树，包括基础的链路配置、链路聚合、MSTP区域配置、根桥选举，以及VRRP负载均衡设置，以确保网络的稳定性和高可用性。通过配置VRRP虚拟IP地址，实现网关冗余，提升网络服务的可靠性。

实验topo

将各设备进行基础配置

1.创建vlan、修改端口类型

将交换机之间连接的接口配置为trunk口并放行，将交换机连接PC的接口配置为access口

SW1

interface GigabitEthernet0/0/3
port link-type trunk
port trunk allow-pass vlan 2 to 4094
#
interface GigabitEthernet0/0/4
port link-type trunk
port trunk allow-pass vlan 2 to 4094
#
interface GigabitEthernet0/0/5
port link-type access
port default vlan 30
SW2

interface GigabitEthernet0/0/3
port link-type trunk
port trunk allow-pass vlan 2 to 4094
#
interface GigabitEthernet0/0/4
port link-type trunk
port trunk allow-pass vlan 2 to 4094
interface GigabitEthernet0/0/1
port link-type access
port default vlan 10

SW4

interface GigabitEthernet0/0/3
port link-type trunk
port trunk allow-pass vlan 2 to 4094
#
interface GigabitEthernet0/0/4
port link-type trunk
port trunk allow-pass vlan 2 to 4094
interface GigabitEthernet0/0/1
port link-type access
port default vlan 20
2.创建链路聚合

SW1

interface GigabitEthernet0/0/1
eth-trunk 1
#
interface GigabitEthernet0/0/2
eth-trunk 1

interface Eth-Trunk1
port link-type trunk
port trunk allow-pass vlan 2 to 4094
mode lacp-static

SW2

interface GigabitEthernet0/0/1
eth-trunk 1
#
interface GigabitEthernet0/0/2
eth-trunk 1

interface Eth-Trunk1
port link-type trunk
port trunk allow-pass vlan 2 to 4094
mode lacp-static

3.mstp配置，端口配置

sw1到sw4配置

stp region-configuration
region-name huawei
instance 10 vlan 10
instance 20 vlan 20
active region-configuration
#

mstp根桥配置

SW1

stp instance 10 root primary
stp instance 20 root secondary
SW2

stp instance 10 root secondary
stp instance 20 root primary

sw3到sw4配置边缘端口

interface GigabitEthernet0/0/1
stp edged-port enable

4.vrrp配置

SW1

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 120
vrrp vrid 10 track interface GigabitEthernet0/0/5 reduced 30 //检测端口
#
interface Vlanif20
ip address 192.168.20.252 255.255.255.0
vrrp vrid 20 virtual-ip 192.168.20.254

SW2

interface Vlanif10
ip address 192.168.10.253 255.255.255.0
vrrp vrid 10 virtual-ip 192.168.10.254
#
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
vrrp vrid 20 track interface GigabitEthernet0/0/5 reduced 30 //检测端口
5.静态路由

SW1

ip route-static 0.0.0.0 0.0.0.0 10.0.13.3

SW2

ip route-static 0.0.0.0 0.0.0.0 10.0.23.3

AR1

ip route-static 192.168.10.0 255.255.255.0 10.0.13.1
ip route-static 192.168.10.0 255.255.255.0 10.0.23.2
ip route-static 192.168.20.0 255.255.255.0 10.0.13.1
ip route-static 192.168.20.0 255.255.255.0 10.0.23.2
