          Locator/ID Separation Protocol (LISP) Control-Plane
                     draft-ietf-lisp-rfc6833bis-06

Abstract

   This document describes the Control-Plane and Mapping Service for the
   Locator/ID Separation Protocol (LISP), implemented by two new types
   of LISP-speaking devices -- the LISP Map-Resolver and LISP Map-Server
   -- that provides a simplified "front end" for one or more Endpoint ID
   to Routing Locator mapping databases.

   By using this control-plane service interface and communicating with
   Map-Resolvers and Map-Servers, LISP Ingress Tunnel Routers (ITRs) and
   Egress Tunnel Routers (ETRs) are not dependent on the details of
   mapping database systems, which facilitates modularity with different
   database designs.  Since these devices implement the "edge" of the
   LISP infrastructure, connect directly to LISP-capable Internet end
   sites, and comprise the bulk of LISP-speaking devices, reducing their
   implementation and operational complexity should also reduce the
   overall cost and effort of deploying LISP.
