Abstract

   IPv6 interfaces are required to have a link-local address that is
   unique on the link.  Nodes normally derive a link local address
   through the use of IPv6 Stateless Address Autoconfiguration (SLAAC)
   and employ Duplicate Address Detection (DAD) to ensure uniqueness.
   This document presents a method for a node that obtains a delegated
   prefix to statelessly construct a link-local address (known as the
   "AERO address") that is assured to be unique on the link.

1.  Introduction

   IPv6 interfaces are required to have a link-local address that is
   unique on the link [RFC8200][RFC4861].  Nodes normally derive a link
   local address through the use of IPv6 StateLess Address Auto
   Configuration (SLAAC) and employ Duplicate Address Detection (DAD)
   [RFC4862] to ensure uniqueness.  This document presents a method for
   a node that obtains a delegated prefix to statelessly construct a
   link-local address (known as the "AERO address") that is assured to
   be unique on the link.

   Nodes that construct AERO addresses must have assurance that all
   other nodes on the link employ the same address autoconfiguration
   method.  This can be assured on links for which there is an
   "IPv6-over-(foo)" specfication that mandates use of AERO addresses
   (e.g., see: [I-D.templin-aerolink]).  Other link types can be
   administratively coordinated (e.g., via network management) to assure
   that only AERO addresses are used.

2.  Terminology

   The terminology in the normative references applies.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].  Lower case
   uses of these words are not to be interpreted as carrying RFC2119
   significance.
