2.  Abstract

   This memo describes additions to ARP that will allow a station to
   request a protocol address corresponding to a given hardware address.
   Specifically, this applies to Frame Relay stations that may have a
   Data Link Connection Identifier (DLCI), the Frame Relay equivalent of
   a hardware address, associated with an established Permanent Virtual
   Circuit (PVC), but do not know the protocol address of the station on
   the other side of this connection.  It will also apply to other
   networks with similar circumstances.

   This memo replaces RFC 1293.  The changes from RFC 1293 are minor
   changes to formalize the language, the additions of a packet diagram
   and an example in section 7.2, and a new security section.

3.  Conventions

   The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD,
   SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, when they appear in this
   document, are to be interpreted as described in [5].
