Abstract

   The Point-to-Point Protocol (PPP) provides a standard method for
   transporting multi-protocol datagrams over point-to-point links.  PPP
   defines an extensible Link Control Protocol (LCP) and proposes a
   family of Network Control Protocols (NCP) for establishing and
   configuring different network-layer protocols.

   This document defines the NCP for establishing and configuring Remote
   Bridging for PPP links.

   This document obsoletes RFC 2878, which was based on the IEEE
   802.1D-1993 MAC Bridge.  This document extends that specification by
   improving support for bridge control packets.
