注意图中
Vlan 10访问192.168.1.0/24的路径 sw1—sw2—R1,VLAN 20访问192.168.1.0/24的路径sw1—sw3-R1,互为主备，且来回路径一致
配置MSTP，保证VLAN 10的主、备份根分别是SW2、SW3，VLAN 20的主、备份根分别是SW3、SW2
配置VRRP，保证VLAN 10的主、备份网关是SW2、SW3，VLAN 20的主、备份网关分别是SW3、SW2
配置SW2和SW3的互联链路为AP
sw2#sh run

interface AggregatePort 1

interface VLAN 10
no ip proxy-arp
ip address 172.16.10.252 255.255.255.0
vrrp 10 priority 105 如果虚拟ip和接口ip相同，该接口的优先级为255
vrrp 10 ip 172.16.10.254
vrrp 10 track FastEthernet 0/22 -跟踪上行端口，如果上行链路无效，马上掉默认10的优先值
!
interface VLAN 20
no ip proxy-arp
ip address 172.16.20.252 255.255.255.0
vrrp 20 ip 172.16.20.254 -vrrp20未设优先级，默认就是100，sw3设置了105，故sw3是vlan20的master
!
interface VLAN 500

R1的配置，注意返回路由的和路由的优先级
R1# show run

Int fa0/1
No shutdown
Ip add 10.1.1.6 255.255.255.252
Int loopback 0
Ip add 192.168.1.1 255.255.255.0
Ip route 172.16.10.0 255.255.255.0 10.1.1.1
Ip route 172.16.10.0 255.255.255.0 10.1.1.5 20
Ip route 172.16.20.0 255.255.255.0 10.1.1.5
Ip route 172.16.20.0 255.255.255.0 10.1.1.1 20
最后：在接入交换机
1、使用spanning-tree mst configuration进入mst 配置模式
2、使用instance 命令创建实例并和vlan建立映射关系，所有设备的实例及映射关系必须一致，否则就是不同的域
Sw1# show run
vlan 1
vlan 10
vlan 20
spanning-tree
spanning-tree mst configuration
instance 0 vlan 1-19, 21-4094
instance 1 vlan 20
interface FastEthernet 0/1
switchport access vlan 10
!
interface FastEthernet 0/10
switchport access vlan 20
interface FastEthernet 0/22
!
interface FastEthernet 0/23
switchport mode trunk
!
interface FastEthernet 0/24
switchport mode trunk
