Vendor Specific LISP Canonical Address Format (LCAF)
draft-ietf-lisp-vendor-lcaf-04
Abstract
This document describes a new LISP Canonical Address Format (LCAF),
the Vendor Specific LCAF. This LCAF enables organizations to have
internal encodings for LCAF addresses.

1. Introduction
The LISP Canonical Address Format (LCAF) [RFC8060] defines the format
and encoding for different address types that can be used on LISP
[I-D.ietf-lisp-rfc6830bis] [I-D.ietf-lisp-rfc6833bis] 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 used only internally on particular LISP
deployments.
2. Requirements Notation
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
3. 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.
