      DHCPv6_PD, PDP and NDP Implementation in IoT Router (DANIR)

Abstract

   This document provides a description of the implementation of Dynamic
   Host Configuration Protocol version 6 Prefix Delegation, Neighbour
   Discovery Protocol and of the use of the Packet Data Protocol in an
   Internet of Things Router.  This Internet of Things Router is
   connected on a cellular network; it is a DHCPv6-PD Client and it
   requests a /56 pool of prefixes from the server; the DHCPv6-PD server
   is placed in the PGW and is a part of the cellular infrastructure.
   After the pool of prefixes is delegated, the Internet of Things
   Router derives sub-prefixes from the prefix pool; each one of these
   sub-prefixes is aimed at one ingress interface.

   After the Internet of Things Router finishes the network prefix
   assignment procedure, it advertises the network prefixes on the
   ingress links by using the Neighbour Discovery protocol.  Finally,
   when Hosts receive the sub-prefixes via Router Adverticement
   messages, they configure the Global Unique Address with the Stateless
   Address Auto-configuration protocol.

1.  Introduction

   This document describes the implementation of the Dynamic Host
   Configuration Protocol vestion 6 with Prefix Delegation (DHCPv6_PD),
   Neighbour Discovery Protocol (NDP) and usage of the Packet Data
   Protocol (PDP) in an Internet of Things (IoT) Router.

   The use of DHCPv6 Prefix Delegation in LTE networks is overviewed in
   [RFC6653].  It misses several important aspects.

   The router MUST be a node that forwards IP version 6 packets not
