                  LISP EID Block

  Management Guidelines
                 draft-ietf-lisp-eid-block-mgmnt-07.txt for the Locator/ID Separation Protocol (LISP)
                    Endpoint Identifier (EID) Block

Abstract

   This document proposes a framework for the management of the LISP EID
   Address Block. Locator/
   ID Separation Protocol (LISP) Endpoint Identifier (EID) address
   block.  The framework described relies on hierarchical distribution
   of the address space, granting temporary usage of prefixes of such
   space to requesting organizations.

1.  Requirements Notation

   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].

2.  Introduction

   The Locator/ID Separation Protocol (LISP - [RFC6830]) and related
   mechanisms ([RFC6831], [RFC6832], [RFC6833], [RFC6834], [RFC6835],
   [RFC6836], [RFC6837]) separate the IP addressing space into two
   logical spaces, the End-point IDentifier Endpoint Identifier (EID) space and the Routing
   LOCator
   Locator (RLOC) space.  The first space is used to identify
   communication end-points, endpoints, while the second is used to locate EIDs in
   the Internet routing infrastructure topology.

   The document [I-D.ietf-lisp-eid-block] requested

   [RFC7954] requests an IPv6 address block reservation exclusively for
   use as EID prefixes in the LISP experiment.  The rationale, intent,
   size, and usage of the EID address block are described in [I-D.ietf-lisp-eid-block]. [RFC7954].

   This document proposes a management framework for the registration of
   EID prefixes from that block, allowing the requesting organization
   exclusive use of those EID prefixes limited to the duration of the
   LISP experiment.

2.  Requirements Notation

   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].

3.  Definition of Terms

   This document does not introduce any new terms related to the set of
   LISP Specifications ([RFC6830], [RFC6831], [RFC6832], [RFC6833],
   [RFC6834], [RFC6835], [RFC6836], [RFC6837]), but assumes that the
   reader is familiar with the LISP terminology.
   [I-D.ietf-lisp-introduction]  [INTRO] provides an
   introduction to the LISP technology, including its terminology. .

4.  EID Prefix Registration Policy

   The request for registration of EID prefixes MUST be done under the
   following policies:

   1.  EID prefixes are made available in the reserved space on a
       temporary basis and for experimental uses.  The requester of an
       experimental prefix MUST provide a short description of the
       intended use or experiment that will be carried out (see
       Section 6).  If the prefix will be used for activities not
       documented in the original description, the renewal of the
       registration may be denied.

   2.  EID prefix registrations MUST be renewed on a regular basis to
       ensure their use by active participants in the experiment.  The
       registration period is 12 months.  A renewal SHOULD NOT cause a
       change in the EID prefix registered in the previous request.  The
       conditions of registration renewal are to be the same as the
       conditions of the first EID prefix registration request.

   3.  It is preferable not to reuse that EID prefixes whose registration is
       expired. registrations have
       expired not be reused.  When an EID prefix registration is
       removed from the registry, then the reuse of the EID prefix in a
       subsequent registration on behalf of a different end user should
       be avoided where possible.  If the considerations of overall
       usage of the EID block prefix requires reuse of a previously
       registered EID prefix, then a minimum delay of at least one week
       between removal and subsequent registration SHOULD be applied by
       the registry operator.

   4.  All registrations of EID prefixes cease at the time of the
       expiration of  When the reserved experimental LISP EID Block. block expires, all EID
       prefix registrations expire as well.  The further disposition of
       these prefixes and the associated registry entries is are to be
       specified in the announcement of the cessation of this
       experiment.

5.  EID Prefixes Registration Requirements

   All EID prefix registrations MUST respect satisfy the following requirements:

   1.  All EID prefix registrations MUST use a globally unique EID
       prefix.

   2.  The EID Prefix prefix registration information, as specified in
       Section 6, MUST be collected upon initial registration and
       renewal, and made publicly available through interfaces allowing
       both the retrieval of specific registration details (search) and
       the enumeration of the entire registry contents (e.g., [RFC7481], RDAP
       ([RFC7481]), WHOIS, HTTP, or similar access methods).

   3.  The registry operator MUST permit the delegation of EID prefixes
       in the reverse DNS space to holders of registered EID prefixes.

   4.  Anyone can obtain an entry in the EID prefix registry, on the
       understanding that the prefix so registered is for the exclusive
       use in the LISP experimental network, and that their registration
       details (as specified in Section 6) are openly published in the
       EID prefix registry.

6.  EID Prefix Request Template

   The following is a basic request template for prefix registration so to
   ensure a uniform process.  Such a  This template is inspired by the IANA
   Private IANA's online
   "Private Enterprise Number online request (PEN) Request" form
   (http://pen.iana.org/pen/PenApplication.page).
   <http://pen.iana.org/pen/PenApplication.page>.

   Note that all details in this registration become part of the
   registry and will be published in the LISP EID Prefix Registry. Registry
   managed by RIPE NCC.

   The EID Prefix Request template MUST at a minimum contain:

   1.  Organization (In the case of individuals requesting an EID prefix
       prefix, this section can be left empty)

       (a)  Organization Name

       (b)  Organization Address
       (c)  Organization Phone

       (d)  Organization WebSite Website

   2.  Contact Person (Mandatory)

       (a)  Name

       (b)  Address

       (c)  Phone

       (d)  Fax (optional)

       (e)  Email

   3.  EID Prefix Request (Mandatory)

       (a)  Prefix Size

         +  Expressed as an address prefix length.

       (b)  Prefix Size Rationale

       (c)  Lease Period

         +  Note Well: well: All EID Prefix registrations will be valid until
            the earlier date of 12 months from the date of registration
            or MMMM/YYYY3. August 2019.

         +  All registrations may be renewed by the applicant for
            further 12 month 12-month periods, ending on MMMM/YYYY3. August 2019.

         +  According to the 3+3 year experimentation plan, defined in [I-D.ietf-lisp-eid-block],
            [RFC7954], all registrations MUST end by MMMM/YYYY3, August 2019, unless
            the IETF community decides to grant a permanent LISP EID
            address block.  In the latter case, registrations following
            the present document policy MUST end by MMMM/YYYY6 August 2022 and a
            new policy (to be decided - -- see Section 7) will apply afterwards.
            thereafter.

   4.  Experiment Description

       (a)  Experiment and Deployment Description

       (b)  Interoperability with existing Existing LISP deployments Deployments

       (c)  Interoperability with Legacy Internet
   5.  Reverse DNS Servers (Optional)

       (b)  Name server address: Server Address

       (c)  Name server name: Server Name

       (d)  Name server address: Server Address

       (Repeat if necessary)

7.  Policy Validity Period

   Policy

   The policy outlined in the present document is tied to the existence
   of the experimental LISP EID block requested in
   [I-D.ietf-lisp-eid-block] [RFC7954] and is
   valid until MMMM/YYYY3. August 2019.

   If the IETF decides to transform the block in into a permanent
   allocation, the usage period reserved for the LISP EID block reserved usage period will be
   extended for three years (until MMMM/YYYY6) so as August 2022) to give allow time to for the
   IETF to define, following the policies outlined in [RFC5226], the
   final size of the EID block and create a transition plan, while the
   policy in the present document will still apply.

   Note that, as stated in [I-D.ietf-lisp-eid-block], [RFC7954], the transition of the EID block
   into a permanent allocation has the potential to pose policy issues
   (as recognized in [RFC2860], section 4.3) and hence Section 4.3); hence, discussion with the
   IANA, the RIR Regional Internet Registry (RIR) communities, and the IETF
   community will be necessary to determine the appropriate policy for
   permanent EID prefix management, which will be effective after MMMM/YYYY6.

   [RFC Editor: please replace MMMM and all its occurrences in the
   document with the month of publication of [I-D.ietf-lisp-eid-block]
   as RFC.]

   [RFC Editor: please replace YYYY0 and all its occurrences in the
   document with the year of publication of [I-D.ietf-lisp-eid-block] as
   RFC.]

   [RFC Editor: please replace YYYY3 and all its occurrences in the
   document with the year of publication of [I-D.ietf-lisp-eid-block] as
   RFC plus 3 years, e.g., if published in 2016 then put 2019.]

   [RFC Editor: please replace YYYY6 and all its occurrences in the
   document with the year of publication of [I-D.ietf-lisp-eid-block] as
   RFC plus 6 years, e.g., if published in 2016 then put 2022.] August
   2022.

8.  Security Considerations

   This document does not introduce new security threats in the LISP
   architecture nor in the Legacy Internet architecture.

   For accountability reasons and in line with the security
   considerations in [RFC7020], each registration request MUST contain
   accurate information on about the requesting entity (company,
   institution, individual, etc.) and valid and accurate contact
   information of a referral person (see Section 6).

9.  IANA Considerations

   IANA allocated the following IPv6 address block for experimental use
   as the LISP EID prefix [I-D.ietf-lisp-eid-block]: [RFC7954]:

   o  Address Block: 2001:5::/32

   o  Name: EID Space for LISP

   o  RFC: [I-D.ietf-lisp-eid-block] [RFC7954]

   o  Further Details details are at: http://www.iana.org/assignments/
      iana-ipv6-special-registry/iana-ipv6-special-registry.xhtml

   In order to www.iana.org/assignments/iana-ipv6-
      special-registry

   To grant requesting organisations organizations and individuals exclusive use of
   EID prefixes out of such this reserved block (limited to the duration of
   the LISP experiment as outlined in Section 7) 7), there is an
   operational requirement for an EID registration service.

   Provided that the policies and requirements outlined in Section Sections 4,
   Section
   5, and Section 6 are respected, satisfied, EID prefix registration is accorded based on
   a "First Come First Served" basis.

   There is no hard limit in to the number of registrations an organization
   or individual can submit submit, as long as the information described in
   Section 6 is provided, in particular point 4: "Experiment
   Description".

   For the duration defined in [I-D.ietf-lisp-eid-block] [RFC7954], RIPE NCC will manage the the LISP
   EID prefix as described herein.  Therefore, this document has no IANA
   actions.

10.  Procedures to be followed Followed by RIPE NCC

   RIPE NCC will provide the registration service following the EID
   Prefix Registration Policy (Section 4) and the EID Prefix
   Registration Requirements (Section 5) provided in this document.  The
   request form provided by RIPE NCC will include at least the
   information from the template in Section 6.  RIPE NCC will make
   publicly available all
   received requests. requests publicly available.  While this document does not suggests
   suggest any minimum allocation size, size; RIPE NCC is allowed to introduce
   such a minimum size for management purposes.

   D. Saucez during WG LC.
