   4 # This test is for checking VXLAN MDB functionality. The topology consists of
   5 # two sets of namespaces: One for the testing of IPv4 underlay and another for
   6 # IPv6. In both cases, both IPv4 and IPv6 overlay traffic are tested.
   7 #
   8 # Data path functionality is tested by sending traffic from one of the upper
   9 # namespaces and checking using ingress tc filters that the expected traffic
  10 # was received by one of the lower namespaces.
