Abstract

   This document defines a new IPv6 Neighbor Discovery (ND) option
   termed the "Overlay Multilink Network Interface (OMNI) Option".  The
   OMNI option may appear in any IPv6 ND message type; it is processed
   by interface types that recognize the option and ignored by all other
   interface types.  The option supports functions such as prefix
   registration and multilink coordination, and is extensible to support
   additional functions in the future.

1.  Introduction

   This document defines a new IPv6 Neighbor Discovery (ND) option
   termed the "Overlay Multilink Network Interface (OMNI) Option".  The
   OMNI option may appear in any IPv6 ND message type; it is processed
   by interface types that recognize the option and ignored by all other
   interface types.  The option supports functions such as prefix
   registration and multilink coordination for interface types such as
   the OMNI interface [I-D.templin-6man-omni-interface], and is
   extensible to support additional functions in the future.

   The following sections discuss the OMNI option format and contents.
   Use cases appear in IPv6 over specific link layer documents such as
   [I-D.templin-6man-omni-interface], where the International Civil
   Aviation Organization (ICAO) has expressed interest in the option in
   support of their Document 9896 [ATN][ATN-IPS].  An IPv6 ND option
   Type number assignment is requested in the IANA Considerations
   section.

2.  Terminology

   The terminology in the normative references applies.  The term
   "underlying interface" refers to one of potentially multiple Layer-2
   interfaces over which a Layer-3 (virtual) interface is configured.
