Abstract
This document describes extentions to the Locator/ID Separation
Protocol (LISP) Data-Plane, via changes to the LISP header, to
support multi-protocol encapsulation.

1. Introduction
The LISP Data-Plane is defined in [I-D.ietf-lisp-rfc6830bis]. It
specifies an encapsulation format that carries IPv4 or IPv6 packets
(henceforth jointly referred to as IP) in a LISP header and outer
UDP/IP transport.
The LISP Data-Plane header does not specify the protocol being
encapsulated and therefore is currently limited to encapsulating only
IP packet payloads. Other protocols, most notably Virtual eXtensible
Local Area Network (VXLAN) [RFC7348] (which defines a similar header
format to LISP), are used to encapsulate Layer-2 (L2) protocols such
as Ethernet.
This document defines an extension for the LISP header, as defined in
[I-D.ietf-lisp-rfc6830bis], to indicate the inner protocol, enabling
