                 LISP Control-Plane Multicast Signaling
                  draft-farinacci-lisp-mr-signaling-04

Abstract

   This document describes an alternate method to signal multicast tree
   building among xTRs in multicast capable LISP sites.  This approach
   avoids the need to run a multicast routing protocol on the LISP
   overlay.

2.  Introduction

   The Locator/ID Separation Architecture [RFC6830] provides a mechanism
   to separate out Identification and Location semantics from the
   current definition of an IP address.  By creating two namespaces, an
   Endpoint ID (EID) namespace used by sites and a Routing Locator
