Title:
  Internal Vlan assignment issue in Metaplugin while provisioning
  network

Status in neutron:
  Invalid

Bug description:
  Hi ,

  When creating the subnet for networks , few subnet's DHCP tap interfaces were being set to  internal Vlan tag  4095 ,which is a dead vlan tag and inappropriate. But its not the same case for other networks where the Vlan tag was between 1 to 4094 the valid vlan range. 
  So wherever the 4095 is not assigned the network connectivity is fine and the Vm's are able to get the DHCP ip's.

  This happens randomly.  I have isolated this by testing OVS plugin
  first and ensured no issues in network provisioning, then I tested the
  metaplugin with OVS, encountered the mentioned issue.

  Sample output:

  Bridge br-int
          Port "tapc5b0d0bd-e6"    -- dhcp tap
              tag: 4095
              Interface "tapc5b0d0bd-e6"

  
  Please let me know any further logs are needed.
