                 Locator/ID Separation Protocol (LISP):
  Shared Extension Message & IANA Registry for Packet Type Allocations

Abstract

   This document specifies a Locator/ID Separation Protocol (LISP)
   shared message type for defining future extensions and conducting
   experiments without consuming a LISP packet type codepoint for each
   extension.  It also defines a registry for LISP Packet Type
   allocations, thus updating RFC 6830.

1.  Introduction

   The Locator/ID Separation Protocol (LISP) base specification,
   [RFC6830], defines a set of primitives that are identified with a
   packet type code.  Several extensions have been proposed to add more
   LISP functionalities.  For example, new message types are proposed in
   [LISP-DDT], [LISP-MN-EXT], [LISP-BULK], [NAT-LISP], or
   [LISP-SUBSCRIBE].  It is expected that additional LISP extensions
   will be proposed in the future.

   In order to ease the tracking of LISP message types, this document
   proposes to create a "LISP Packet Types" IANA registry (see
   Section 5).

   Because of the limited type space [RFC6830] and the need to conduct
   experiments to assess new LISP extensions, this document specifies a
   shared LISP extension message type and proposes a procedure for
   registering LISP shared extension sub-types (see Section 3).

   Concretely, one single LISP message type code is dedicated to future
   LISP extensions; sub-types are used to uniquely identify a given LISP
   extension making use of the shared LISP extension message type.
   These identifiers are selected by the author(s) of the corresponding
   LISP specification that introduces a new LISP extension message type.
