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.boucadair-lisp-subscribe], or
[I-D.boucadair-lisp-ms-assisted-forwarding]. 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 identifiers (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; experiment identifiers 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| Experiment ID | experiment-specific |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
// experiment-specific //

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
Figure 1: Common LISP Experimental Message Type
The "Experiment ID" 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].
Boucadair & Jacquenet Expires December 26, 2016 [Page 3]
Internet-Draft LISP Packet Type Allocations June 2016
The value 15 is reserved for Experimental Use [RFC5226].
4.2. Experiment IDs
IANA is requested to create a "LISP Experimental Message Experiment
Identifiers" 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.
5. Acknowledgments
This work is partly funded by ANR LISP-Lab project #ANR-13-INFR-
009-X.
The shared experiment ID is inspired by [RFC6994].
Many thanks to Luigi Iannone for the review.
