                NBMA Address Resolution Protocol (NARP)

Status of this Memo

   This memo defines an Experimental Protocol for the Internet
   community.  This memo does not specify an Internet standard of any
   kind.  Discussion and suggestions for improvement are requested.
   Distribution of this memo is unlimited.

IESG Note:

   Note that the work contained in this memo does not describe an
   Internet standard.  This work represents an early stage in the
   ongoing efforts to resolve direct communication over NBMA subnets.
   It is a suitable experimental protocol for early deployment.  It is
   expect that it will be superceded by other work being developed
   within the IETF.

Abstract

   This document describes the NBMA Address Resolution Protocol (NARP).
   NARP can be used by a source terminal (host or router) connected to a
   Non-Broadcast, Multi-Access link layer (NBMA) network to find out the
   NBMA addresses of the a destination terminal provided that the
   destination terminal is connected to the same NBMA network.  Although
   this document focuses on NARP in the context of IP, the technique is
   applicable to other network layer protocols as well.  This RFC is a
   product of the Routing over Large Clouds Working Group of the IETF.

1. Introduction

   The NBMA Address Resolution Protocol (NARP) allows a source terminal
   (a host or router), wishing to communicate over a Non-Broadcast,
   Multi-Access link layer (NBMA) network, to find out the NBMA
   addresses of a destination terminal if the destination terminal is
   connected to the same NBMA network as the source.
