一.创建vlan并修改MSTP

vlan batch

stp mode mstp

二.接口配置

interface gigabitethernet 0/0/1

port link-type trunk

port trunk allow-pass vlan 10 20

三.MSTP配置

stp region-configuration

region-name MST-LAB

revision-level 1

instance 1 vlan 10

instance 2 vlan 20

active region-configuration

四.创建虚拟接口

intterface vlanif 10

ip address 192.168.1.1 24

vrrp vrid 1 virtual-ip 192.168.1.254

vrrp vrid 1 priority 120

vrrp vrid 1 track interface gigabiethernet 0/0/4 reduced 30
