 Locator/ID Separation Protocol (LISP): Shared Extension Message & IANA
                  Registry for Packet Type Allocations
                   draft-boucadair-lisp-rfc8113bis-00

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.

   This document obsoletes RFC 8113.

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.  It is expected that additional LISP extensions
   will be proposed in the future.

   The "LISP Packet Types" IANA registry (see Section 5) is used to ease
   the tracking of LISP message types.

   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 describes 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.

2.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].
