1.  Introduction

   The Locator/ID Separation Protocol (LISP, [RFC6830] ) base
   specification 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
   [I-D.ietf-lisp-ddt], [I-D.zhao-lisp-mn-extension],
   [I-D.boucadair-lisp-bulk], [I-D.ermagan-lisp-nat-traversal], or
   [I-D.boucadair-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 4).

   Because of the limited type space [RFC6830], this document specifies
   a shared LISP message type for experimentation purposes and proposes
   a procedure for registering LISP experiment sub-types (see Section 2)
   that make use of additional LISP capabilities associated with this
   message type.  Concretely, one single LISP message type code is
   dedicated to experiments; sub-types are used to uniquely identify a
   given LISP experimental message.  These identifiers are selected by
   the author(s) of the corresponding LISP specification that introduces
   a new experimental message type.

2.  LISP Message Type for Experimentations

   Figure 1 depicts a common LISP experimental message type.  The type
   field MUST be set to 15 (see Section 4).

        0                   1                   2                   3
        0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
       +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
       |Type=15|        Sub-type       |  experiment-specific          |
       +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
       //                   experiment-specific                       //
       //                                                             //
       +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

              Figure 1: Common LISP Experimental Message Type

   The "Sub-type" field conveys a unique identifier that is assigned on
   a First Come, First Served (FCFS) basis [RFC5226].  These identifiers
   are registered with IANA (see Section 4.2).

   The exact structure of the 'experiment-specific' portion of the
   message is specified in the corresponding specification document.

3.  Security Considerations

   This document does not introduce any additional security issues other
   than those discussed in [RFC6830].

4.  IANA Considerations

4.1.  LISP Packet Types

   IANA is requested to create a new protocol registry for LISP Packet
   Types, numbered 0-15.  The registry must be initially populated with
   the following values:

   Message                           Code    Reference
   ================================= ==== ===============
   Reserved                           0      [RFC6830]
   LISP Map-Request                   1      [RFC6830]
   LISP Map-Reply                     2      [RFC6830]
   LISP Map-Register                  3      [RFC6830]
   LISP Map-Notify                    4      [RFC6830]
   LISP Encapsulated Control Message  8      [RFC6830]
   LISP Experimental Message         15   [This document]

   The values in the ranges 5-7 and 9-14 can be assigned via Standards
   Action [RFC5226].  Documents that request for a new LISP packet type
   may indicate a preferred value in the corresponding IANA sections.

   The value 15 is reserved for Experimental Use [RFC5226].

4.2.  Sub-Types

   IANA is requested to create a "LISP Experimental Message Sub-types"
   registry.

   Entries are assigned on a FCFS basis.

   The registration procedure should provide IANA with the desired
   codepoint and a point of contact.  Providing a short description
   (together with an acronym, if relevant) of the foreseen usage of the
   experimental message is also encouraged.
