Title:
  SNAT name space is being hosted on all nodes though agent_mode is set
  as dvr

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  SNAT name space is being hosted on all nodes though agent_mode is set
  as dvr

  Here are the steps followed.

  1. one service node with agent_mode=snat
  2. Two compute nodes with agent_mode=dvr
  3. Create an external network. Subnet within it.
  4.  Create a private network & subnet(sub1) within it.
  5 .Create a Distributed Router(DVR)
  6. Set the  external network as gateway to the DVR.
  7. Add the ptivate subnet  (sub1) as interface to the DVR.
  8. Since the service node has the agent_mode as DVR-snat, the snat namespace will sit on this service node.  But the snat namespace is hosted on all 3 nodes(service node with agent_mode=dvr_snat & Compute nodes with agent_mode=dvr)

  
  Expected behavior:
  snat name space should sit only on the node with agent_mode=dvr_snat.
