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

multiple IP hops away from the PaC. The PRE implemented on the
parent node is used for relaying PANA messages between the PaC and
the PAA in this scenario.
