STP (802.1D) PVST

 1. RSTP
    root port
    designated port
    alternative port (root port) - 원래 blocking 이지만 alternative로 만들어둠
    backup port (designated port)

    edge port (listen , learn) 생략

    config)#spanning-tree mode rapid-pvst

 2. MSTP
   
    MST (name, revision, group)
    D1
      spanning-tree mode mst ==> (RSTP 자동 enable)
      spanning-tree mst configuration  
        name BCMSN
        revision 1
        instance 1 vlan 1-500
        instance 2 vlan 500-1000
     
      show spanning-tree mst 1
      show spanning-tree mst 2

      spannign-tree mst 1 root primary
      spanning-tree mst 2 root secondary
     
    STP 1000 ===> STP 2개

      show spanning-tree mst configuration
