Abstract

   This document discusses a framework of supporting multicast traffic
   in a network that uses Network Virtualization Overlays (NVO3). Both
   infrastructure multicast and application-specific multicast are
   discussed. It describes the various mechanisms that can be used for
   delivering such traffic as well as the data plane and control plane
   considerations for each of the mechanisms.
