STP 生成树协议


  1. 1.将所有交换机创建trunk链路模式&＃xff1a;
    [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
