Request for Comments: 1132                          The Wollongong Group
                                                           November 1989


   A Standard for the Transmission of 802.2 Packets over IPX Networks


Status of this Memo

   This document specifies a standard method of encapsulating 802.2 [1]
   packets on networks supporting Novell's Internet Packet Exchange
   Protocol [2] (IPX).  It obsoletes earlier documents detailing the
   transmission of Internet packets over IPX networks.  It differs from
   these earlier documents in that it allows for the transmission of
   multiple network protocols over IPX and for the transmission of
   packets through IPX bridges.  Distribution of this memo is unlimited.

Introduction

   The goal of this specification is to allow compatible and
   interoperable implementations for transmitting Internet packets such
   as the Internet Protocol [3] (IP) and Address Resolution Protocol [4]
   (ARP) as well as the Connectionless-mode Network Protocol [5] (CLNP)
   over IPX networks.

   IPX is a proprietary standard developed by Novell derived from
   Xerox's Internet Datagram Protocol [6] (IDP). Defining the
   encapsulation of the IEEE 802.2 Data Link Layer Standard over IPX in
   terms of yet another 802.X Physical Layer standard allows for the
   transmission of IP Datagrams as described in RFC 1042 [7].  This
   document will focus on the implementation of that RFC over IPX
   networks.

Description

   In general, this specification allows IPX networks to be used to
   support any network protocol which can use the IEEE 802.2 Data Link
   Layer specification.

   More specifically, IPX networks may be used to support IP networks
   and subnetworks of any class.  By encapsulating IP datagrams within
   IPX datagrams and assigning IP numbers to the hosts on a IPX network,
   IP-based applications are supported on these hosts.  The addition of
   an IP Gateway capable of encapsulating IP packets within 802.IPX
   datagrams would allow those hosts on an IPX network to communicate
   with the Internet.
