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.
