                      Label Distribution Using ARP
                      draft-kompella-mpls-larp-06

Abstract

   This document describes extensions to the Address Resolution Protocol
   to distribute MPLS labels for IPv4 and IPv6 host addresses.
   Distribution of labels via ARP enables simple plug-and-play operation
   of MPLS.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

   The term "server" will be used in this document to refer to an ARP/
   L-ARP server; the term "host" will be used to refer to a compute
   server or other device acting as an ARP/L-ARP client.
