1.  Introduction

   The Locator/ID Separation Protocol (LISP) [I-D.ietf-lisp-rfc6833bis]
   splits current IP addresses in two different namespaces, Endpoint
   Identifiers (EIDs) and Routing Locators (RLOCs).  LISP uses a map-
   and-encap approach that relies on (1) a Mapping System (basically a
   distributed database) that stores and disseminates EID-RLOC mappings
   and on (2) LISP tunnel routers (xTRs) that encapsulate and
   decapsulate data packets based on the content of those mappings.

   ITRs/RTRs/PITRs pull EID-to-RLOC mapping information from the Mapping
   System by means of an explicit request message.
   [I-D.ietf-lisp-rfc6833bis] indicates how ETRs can tell ITRs/RTRs/
   PITRs about mapping changes.  This document presents a Publish/
   Subscribe (PubSub) extension in which the Mapping System can notify
   ITRs/RTRs/PITRs about mapping changes.  When this mechanism is used,
   mapping changes can be notified faster and can be managed in the
   Mapping System versus the LISP sites.
