Abstract 

   This document describes how Ethernet VPN (E-VPN) technology can be
   used to interconnect VXLAN or NVGRE networks over an MPLS/IP network.
   This is to provide intra-subnet connectivity at Layer 2 and control-
   plane separation among the interconnected VXLAN or NVGRE networks.
   The scope of the learning of host MAC addresses in VXLAN or NVGRE
   network is limited to data plane learning in this document.
