   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.
