IPv6 Neighbor Discovery Overlay Multilink Network Interface (OMNI)
Option
draft-templin-6man-omni-option-05
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.
