Abstract

   The Locator/ID Separation Protocol (LISP) operation is based on EID
   to RLOC mappings that are exchanged through a mapping system.  The
   mapping system can use the RLOCs included in mapping registrations to
   construct the complete set of RLOC addresses across all xTRs that are
   members of the LISP deployment.  This set can then be made available
   by the mapping system to all the member xTRs.  An xTR can use the
   RLOC set to optimise protocol operation as well as to implement new
   functionality.  This document describes the use of the LISP reliable
   transport session between an xTR and a Map-Server to communicate the
   contents of the RLOC membership set.
