2. Terminology

Ce document met a jour IPv6 Neighbor Discovery et les specifications 6LoWPAN/RPL associees afin qu'un noeud puisse enregistrer un IPv6 prefix aupres de routeurs voisins. Les details de protocole essentiels sont conserves ci-dessous depuis le texte RFC.

2.  Terminology

2.1.  Requirements Language

   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.

2.2.  Inherited Terms and Concepts

   This document uses terms and concepts that are discussed in:

   *  "Neighbor Discovery for IP version 6 (IPv6)" [RFC4861] and

   *  "IPv6 Stateless Address Autoconfiguration" [RFC4862] for the
      Neighbor Solicitation operation,

   *  "Neighbor Discovery Optimization for IPv6 over Low-Power Wireless
      Personal Area Networks (6LoWPANs)" [RFC6775], as well as

   *  "Registration Extensions for IPv6 over Low-Power Wireless Personal
      Area Network (6LoWPAN) Neighbor Discovery" [RFC8505], and

   *  "RPL: IPv6 Routing Protocol for Low-Power and Lossy Networks"
      [RFC6550] for RPL, which is the routing protocol used in LLNs for
      SND.
