    Description

      Broadcast packets are flooded to all nodes while creating VM instance in openstack nodes.

      control node and 2 compute nodes connected to ODL.

      scenario:
      1.created 1 network.
      2.checked initial flow packet counts are zero in all nodes.
      3.created VM instance in control node.
      4.checked flows in all nodes packets are flooded to compute nodes but the tenant network not associated with compute nodes because no VM's created on compute nodes using Network.
      5.created VM instance on compute node1 and checked flows, compute node2 also getting flooded packets but the tenant network not associated with compute node2 because no VM's created on compute node2 using Network.

      DUMP Flows:
      initial flow:
