Vendor Specific LCAF
draft-rodrigueznatal-lisp-vendor-lcaf-00
Abstract
This document describes a new LCAF for LISP, the Vendor Specific
LCAF. This LCAF enables organizations to have internal encodings for
LCAF addresses.

1. Introduction
The LISP Canonical Address Format [RFC8060] defines the format and
encoding for different address types that can be used on LISP
[RFC6830] deployments. However, certain deployments require specific
format encodings that may not be applicable outside of the use-case
for which they are defined. The Vendor Specific LCAF allows
organizations to create LCAF addresses to be internally-only used on
particular LISP deployments.
2. Vendor Specific LCAF
The Vendor Specific LCAF relies on using the IEEE Organizationally
Unique Identifier (OUI) [IEEE.802_2001] to prevent collisions across
vendors or organizations using the LCAF. The format of the Vendor
Specific LCAF is provided below.
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

Vendor Specific LCAF
The Vendor Specific LCAF has the following fields.
Rsvd3: This 8-bit field is reserved for future use. It MUST be
set to 0 on transmit and MUST be ignored on receipt.

Organizationally Unique Identifier (OUI): This is a 24-bit field
that carries the IEEE OUI [IEEE.802_2001] of the organization.
Internal format: This is a variable length field that is left
undefined on purpose. Each vendor or organization can define its
own internal format(s) to use with the Vendor Specific LCAF.
The definition for the rest of the fields can be found in [RFC8060].
The Vendor Specific LCAF type SHOULD not be used in deployments where
different organizations interoperate. If a LISP device receives a
LISP message containing an Vendor Specific LCAF with and OUI it does
not understand, it SHOULD drop the message and a log action MUST be
taken.
3. Security Considerations
TBD.
4. Acknowledgments
TBD.
5. IANA Considerations
Following the guidelines of [RFC5226], this document requests IANA to
update the "LISP Canonical Address Format (LCAF) Types" Registry
defined in [RFC8060] to allocate the following assignment:
+---------+---------------------+-----------+
| Value # | LISP LCAF Type Name | Reference |
+---------+---------------------+-----------+
| 255 | Vendor Specific | Section 2 |
+---------+---------------------+-----------+
