Abstract

   The Point-to-Point Protocol (PPP) [1] provides a standard method for
   transporting multi-protocol datagrams over point-to-point links.

   This document describes how to build PPP sessions and encapsulate PPP
   packets over Ethernet.

Applicability

   This specification is intended to provide the facilities which are
   defined for PPP, such as the Link Control Protocol, Network-layer
   Control Protocols, authentication, and more.  These capabilities
   require a point-to-point relationship between the peers, and are not
   designed for the multi-point relationships which are available in
   Ethernet and other multi-access environments.

   This specification can be used by multiple hosts on a shared,
   Ethernet to open PPP sessions to multiple destinations via one or
   more bridging modems.  It is intended to be used with broadband
   remote access technologies that provide a bridged Ethernet topology,
   when access providers wish to maintain the session abstraction
   associated with PPP.
