     Protocol for Carrying Authentication for Network Access (PANA)
                             Relay Element

Abstract

   This document specifies Protocol for carrying Authentication for
   Network Access (PANA) Relay Element functionality, which enables PANA
   messaging between a PANA Client (PaC) and a PANA Authentication Agent
   (PAA) where the two nodes cannot reach each other by means of regular
   IP routing.

1.  Introduction

   Protocol for carrying Authentication for Network Access (PANA)
   [RFC5191] is a UDP-based protocol to perform Extensible
   Authentication Protocol (EAP) authentication between a PANA Client
   (PaC) and a PANA Authentication Agent (PAA).

   This document specifies PANA Relay Element (PRE) functionality, which
   enables PANA messaging between a PaC and a PAA where the two nodes
   cannot reach each other by means of regular IP routing.  For example,
   in ZigBee IP [ZIGBEEIP] that uses 6LoWPAN [RFC4944], a joining node
   (PaC) can only use a link-local IPv6 address to communicate with a
   parent node prior to PANA authentication.  The PAA typically resides
   in a 6LowPAN Border Router (6LBR) [6LoWPAN-ND], which is often

   parent node is used for relaying PANA messages between the PaC and
