    pvst

    Rohan Jadhav

      in pvst, there is seperate spanning tree for each vlan

      there 3 switches

      sw0 ,  sw1 and sw2

      3 vlans

      vlan 1, vlan 2 and vlan 3

       

       

      sw0 0007.ECBB.A165

       

      sw1 0090.21D4.E069

       

      sw2 0002.4A6A.2985

       

      i have enable pvst for each vlan

      for vlan 1 , sw2  is the root  bridge

      now for vlan 2 the bid of switches will remain same as it was in vlan 1 or it going to change

      because i think in pvst there is seperate spanning tree fro each vlan

      so for vlan 2 and vlan 3 how root bridge election will happen
