Abstract

   This document extends [I-D.ietf-lisp-rfc6833bis] to allow Map Servers
   to send SMR messages.

   This extension is intended to be used in some SDN deployments that
   use LISP as a southbound protocol with (P)ITRs that are compliant
   with [I-D.ietf-lisp-rfc6833bis].  In this use-case mapping updates do
   not come from ETRs, but rather from a centralized controller that
   pushes the updates directly to the Mapping System.  In such
   deployments, Map Servers will benefit from having a mechanism to
   inform directly (P)ITRs about updates in the mappings they are
   serving.  Although implementations of this extension exist, this
   extension is deprecated by [I-D.ietf-lisp-pubsub] and it is being
   documented for informational purposes.  Newer implementations should
   look into [I-D.ietf-lisp-pubsub] to support PubSub in LISP
   deployments.

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 in two entities, the Mapping System
   and the Tunnel Routers.  The Tunnel Routers are deployed at LISP
   sites edge points and perform encapsulation and decapsulation of LISP
   data packets.  The Mapping System is a distributed database that
   stores and disseminates EID-RLOC bindings across different Map-
   Servers.  LISP Tunnel Routers keep a cache of EID-RLOC mappings
   pulled from the Mapping System.

   There are several ways to keep this cache updated as described in
   [I-D.ietf-lisp-rfc6833bis].  Among them, the Solicit Map-Request
   (SMR) message allows to explicitly signal (P)ITRs to let them know
