STP 生成树协议

1. 1.将所有交换机创建trunk链路模式：
   [Huawei]port-group 1
   [Huawei-port-group-1]group-member GigabitEthernet0/0/01 to GigabitEthernet 0/0/5
   [Huawei-port-group-1]port link-type trunk
   [Huawei-port-group-1]port trunk allow-pass vlan all
   
   
   
   2.将所有交换机创建4个vlan
   
   [Huawei]vl batch 10 20 30 40
   
   3.进入区域模式 创建树并将vlan加入树 激活
   [Huawei]stp region-configuration
   [Huawei-mst-region]region-name 111
   [Huawei-mst-region]instance 1 vlan 10 20
   [Huawei-mst-region]instance 2 vlan 30 40
   [Huawei-mst-region]active region-configuration
   
   4.将树设置优先级
   [Huawei]stp instance 1 root ?
    主 primary    Primary root switch
     副 secondary  Secondary root switch
   
   [Huawei]stp instance 1 root primary
   [Huawei]stp instance 2 root secondary
   
   
   [Huawei]stp instance 1 root secondary
   [Huawei]stp instance 2 root primary
