   9 # Tests performed:
  10 # - Peering OpenDaylight with Quagga:
  11 #   - Set up a Quagga instance in the functest container
  12 #   - Start a BGP router with OpenDaylight
  13 #   - Add the functest Quagga as a neighbor
  14 #   - Verify that the OpenDaylight and functest Quaggas peer
  15 # - Exchange routing information with Quagga:
  16 #   - Create a network, instance and BGPVPN in OpenStack
  17 #   - Verify the route to the instance is present in the OpenDaylight FIB
  18 #   - Verify that the functest Quagga also learns these routes
