   2 Documentation       Test Suite for vni-based-l2-l3-nat:
   3 ...                 This feature attempts to realize the use of VxLAN VNI
   4 ...                 (Virtual Network Identifier) for VxLAN tenant traffic
   5 ...                 flowing on the cloud data-network. This is applicable
   6 ...                 to L2 switching, L3 forwarding and NATing for all VxLAN
   7 ...                 based provider networks. In doing so, it eliminates the
   8 ...                 presence of LPort tags, ELAN tags and MPLS labels on the
   9 ...                 wire and instead, replaces them with VNIs supplied by the
  10 ...                 tenant’s OpenStack.
