RFC 6831 (LISP for Multicast) states: 
"The fundamental multicast forwarding model is to encapsulate a multicast packet into another multicast packet"

So LISP assumes that the underlay network supports some sort of IP multicast scheme. 

In NVO3 environment, especially in data center environment, the underlay network may not necessarily support IP multicast. draft-ghanwani-nvo3-app-mcast-framework-01 describes various mechanisms for forwarding tenant multicast traffic without the underlay network supporting the multicast protocols. 

We appreciate your feedback.

   This draft discusses the framework of supporting applications
   specific multicast traffic, i.e. the non ARP/ND related
   multicast/broadcast traffic, in a network that uses Network
   Virtualization using Overlays over Layer 3 (NVO3). It describes the
   various mechanisms and considerations that can be used for
   delivering those application specific multicast traffic in networks
   that use NVO3.


Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
