具体配置如下

将SW0作为VLAN10的根交换机，G0/1作为根端口，G0/2作为备端口
将SW1作为VLAN20的根交换机，G0/2作为根端口，G0/1作为备端口.

//SW0 上具体配置：
    conf t
    vtp mode server
    vtp domain 123
    vtp password 456
    vlan 10
    vlan 20
    int f0/1
    sw mo ac
    sw ac vlan 10
    exit
    int f0/2
    sw mo ac 
    sw ac vlan 20
    exit
    int vlan 10
    ip add 192.168.10.1 255.255.255.0
    no shut
    exit
    int vlan 20
    ip add 192.168.20.1 255.255.255.0
    no shut
    exit
   spanning-tree vlan 10 priority 4096
   spanning-tree vlan 20 priority 8192
 int g0/1
 switchport mode trunk
 spanning-tree vlan 10 port-priority 16
 spanning-tree vlan 20 port-priority 240
interface GigabitEthernet0/2
 switchport mode trunk
 spanning-tree vlan 20 port-priority 16
 spanning-tree vlan 10 port-priority 240
//SW1配置如下：
conf t
    vtp mode client 
    vtp domain 123
    vtp password 456
    vlan 10
    vlan 20
    int f0/1
    sw mo ac
    sw ac vlan 10
    exit
    int f0/2
    sw mo ac 
    sw ac vlan 20
    exit
    int vlan 10
    ip add 192.168.10.1 255.255.255.0
    no shut
    exit
    int vlan 20
    ip add 192.168.20.1 255.255.255.0
    no shut
    exit
   spanning-tree vlan 10 priority 8192
   spanning-tree vlan 20 priority 4096
 int g0/1
 switchport mode trunk
 spanning-tree vlan 10 port-priority 240
 spanning-tree vlan 20 port-priority 16
interface GigabitEthernet0/2
 switchport mode trunk
 spanning-tree vlan 20 port-priority 240
 spanning-tree vlan 10 port-priority 16

pc 配置如图：

验证结果

断掉一个接口看是否能够正常通信，再show spanning-tree 进行查看
