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.

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] Boucadair & Jacquenet Expires February 2, 2017 [Page 3] Internet-Draft LISP Packet Type Allocations August 2016 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. 5.
