1.  Introduction

   The LISP architecture and protocols [RFC9300] introduces two new
   numbering spaces, Endpoint Identifiers (EIDs) and Routing Locators
   (RLOCs) which are intended to replace most use of IP addresses on the
   Internet.  To provide flexibility for current and future
   applications, these values can be encoded in LISP control messages
   using a general syntax that includes Address Family Identifier (AFI).

   The length of the value field, which represents the address encoding,
   is implicit in the type of address that follows.  For AFI 17, a
   Distinguished Name can be encoded.  A name can be a variable length
   field so the length cannot be determined solely from the AFI value
   17.  This draft defines a termination character, an 8-bit value of 0
   to be used as a string terminator so the length can be determined.

   LISP Distinguished Names are useful when encoded either in EID-
   Records or RLOC-records in LISP control messages.  As EIDs, they can
   be registered in the mapping system to find resources, services, or
   simply used as a self-documenting feature that accompany other
   address specific EIDs.  As RLOCs, Distinguished Names, along with
   RLOC specific addresses and parameters, can be used as labels to
   identify equipment type, location, or any self-documenting string a
   registering device desires to convey.

2.  Definition of Terms

   Address Family Identifier (AFI):  a term used to describe an address
      encoding in a packet.  An address family is currently defined for
      IPv4 or IPv6 addresses.  See [IANA-ADDRESS-FAMILY-REGISTRY] for
      details on other types of information that can be AFI encoded.

3.  Distinguished Name Format

   An AFI=17 Distinguished Name is encoded as:

     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

    +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

   The string of characters are encoded in the ASCII character-set
   definition [RFC0020].

   When Distinguished Names are encoded for EIDs, the EID Mask-Len
   length of the EIDs as they appear in EID-Records for all LISP control
   messages [RFC9301] is the length of the string in bits (including the
   null 0 octet).  Where Distinguished Names are encoded anywhere else
   (i.e., nested in LCAF encodings [RFC8060]), then any length field is
   the length of the ASCII string including the null 0 octet in units of
   octets.

4.  Mapping System Lookups for Distinguished Name EIDs

   Distinguished Name EID lookups MUST carry as an EID Mask-Len length
   equal to the length of the name string.  This instructs the mapping
   system to do either an exact match or longest match lookup.

   If the Distinguished Name EID is registered with the same length as
   the length in a Map-Request, the Map-Server (when configured for
   proxy Map-Replying) returns an exact match lookup with the same EID
   Mask-Len length.  If a less specific name is registered, then the
   Map-Server returns the registered name with the registered EID Mask-
   Len length.

   For example, if the registered EID name is "ietf" with EID Mask-Len
   of 40 bits (the length of string "ietf" plus the null octet is 5
   octets), and a Map-Request is received for EID name "ietf.lisp" with
   an EID Mask-Len of 80 bits, the Map-Server will return EID "ietf"
   with length of 40 bits.

5.  Example Use-Cases

   This section identifies three specific use-cases examples for the
   Distinguished Name format.  Two are used for an EID encoding and one
   for an RLOC-record encoding.  When storing public keys in the mapping
   system, as in [I-D.ietf-lisp-ecdsa-auth], a well-known format for a
   public-key hash can be encoded as a Distinguished Name.  When street
   location to GPS coordinate mappings exist in the mapping system, as

Farinacci                Expires 6 February 2025                [Page 4]
Internet-Draft      LISP Distinguished Name Encoding         August 2024

   in [I-D.ietf-lisp-geo], the street location can be a free form ASCII
   representation (with whitespace characters) encoded as a
   Distinguished Name.  An RLOC that describes an Ingress or Egress
   Tunnel Router (xTR) behind a NAT device can be identified by its
   router name, as in [I-D.farinacci-lisp-lispers-net-nat].  In this
   case, Distinguished Name encoding is used in NAT Info-Request
   messages after the EID-prefix field of the message.

6.  Name Collision Considerations

   When a Distinguished Name encoding is used to format an EID, the
   uniqueness and allocation concerns are no different than registering
   IPv4 or IPv6 EIDs to the mapping system.  See [RFC9301] for more
   details.  Also, the use-case documents specified in Section 5 of this
   specification provide allocation recommendations for their specific
   uses.

   It is RECOMMENDED that each use-case register their Distinguished
   Names with a unique Instance-ID.  For any use-cases which require
   different uses for Distinguish Names within an Instance-ID MUST
   define their own Instance-ID and structure syntax for the name
   registered to the Mapping System.  See the encoding procedures in
   [I-D.ietf-lisp-vpn] for an example.

7.  Security Considerations

   There are no security considerations.

8.  IANA Considerations

   The code-point values in this specification are already allocated in
   [IANA-ADDRESS-FAMILY-REGISTRY].

9.  Sample LISP Distinguished Name (DN) Deployment Experience

   Practical implementations of the LISP Distinguished Name
   specification have been running in production networks for some time.
   The following sections provide some examples of its usage and lessons
   gathered out of this experience.

9.1.  DNs to Advertise Specific Device Roles or Functions

   In a practical implementation of
   [I-D.ietf-lisp-site-external-connectivity] on LISP deployments,
   routers running as Proxy Egress Tunnel Routers (Proxy-ETRs) register
   their role with the Mapping System in order to attract traffic
   destined for external networks.  Practical implementations of this
   functionality make use of a Distinguished Name as an EID to identify

Farinacci                Expires 6 February 2025                [Page 5]
Internet-Draft      LISP Distinguished Name Encoding         August 2024

   the Proxy-ETR role in a Map-Registration.

   In this case all Proxy-ETRs supporting this function register a
   common Distinguished Name together with their own offered locator.
   The Mapping-System aggregates the locators received from all Proxy-
   ETRs as a common locator-set that is associated with this DN EID.
   The Distinguished Name in this case serves as a common reference EID
   that can be requested (or subscribed as per [RFC9437]) to dynamically
   gather this Proxy-ETR list as specified in the LISP Site External
   Connectivity document.

   The use of a Distinguished Name in this case provides descriptive
   information about the role being registered and allows the Mapping
   System to form locator-sets associated to specific role.  These
   locator-sets can be distributed on-demand based on using the shared
   DN as EID.  It also allows the network admin and the Mapping System
   to selectively choose what roles and functions can be registered and
   distributed to the rest of the participants in the network.

9.2.  DNs to Drive xTR On-Boarding Procedures

   Following the LISP reliable transport
   [I-D.ietf-lisp-map-server-reliable-transport], ETRs that plan to
   switch to using a reliable transport to hold registrations first need
   to start with traditional UDP registrations.  The UDP registration
   allows the Map-Server to perform basic authentication of the ETR and
   create the necessary state to permit the reliable transport session
   to be established (e.g., establish a passive open on TCP port 4342
   and add the ETR RLOC to the list allowed to establish a session).

   In the basic implementation of this process, the ETRs need to wait
   until local mappings are available and ready to be registered with
   the Mapping System.  Furthermore, when the mapping system is
   distributed, the ETR requires to have one specific mapping ready to
   be registered with each one of the relevant Map-Servers.  This
   process may delay the onboarding of ETRs with the Mapping System so
   that they can switch to using a reliable transport.  This can also
   lead to generating unnecessary signaling as a reaction to certain
   triggers like local port flaps and device failures.

   The use of dedicated name registrations allows driving this initial
   ETR on-boarding on the Mapping System as a deterministic process that
   does not depend on the availability of other mappings.  It also
   provides more stability to the reliable transport session to survive
   through transient events.

Farinacci                Expires 6 February 2025                [Page 6]
Internet-Draft      LISP Distinguished Name Encoding         August 2024

   In practice, LISP deployments use dedicated Distinguished Names that
   are registered as soon as xTRs come online with all the necessary
   Map-Servers in the Mapping System.  The mapping with the dedicated DN
   together with the RLOCs of each Egress Tunnel Router (ETR) in the
   locator-set is used to drive the initial UDP registration and also to
   keep the reliable transport state stable through network condition
   changes.  On the Map-Server, these DN registrations facilitate
   setting up the necessary state to onboard new ETRs rapidly and in a
   more deterministic manner.

9.3.  DNs for NAT-Traversal

   The open source lispers.net NAT-Traversal implementation
   [I-D.farinacci-lisp-lispers-net-nat] has had 10 years of deployment
   experience using Distinguished Names for documenting xTRs versus Re-
   encapsulating Tunnel Router (RTRs) as they appear in an locator-set.

9.4.  DNs for Self-Documenting RLOC Names

   The open source lispers.net implementation has had 10 years of self-
   documenting RLOC names in production and pilot environments.  The
   RLOC name is encoded with the RLOC address in Distinguished Name
   format.

9.5.  DNs used as EID Names

   The open source lispers.net implementation has had 10 years of
   deployment experience allowing xTRs to register EIDs as Distinguished
   Names.  The LISP Mapping System can be used as a DNS proxy for Name-
   to-EID-address or Name-to-RLOC-address mappings.  The implementation
   also supports Name-to-Public-Key mappings to provide key management
   features in [I-D.ietf-lisp-ecdsa-auth].
