Abstract

The Point-to-Point Protocol (PPP) [6] provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP defines an extensible Link Control Protocol, and proposes a family of Network Control Protocols for establishing and configuring different network-layer protocols.

Abstract

The Point-to-Point Protocol (PPP) [6] provides a standard method for

transporting multi-protocol datagrams over point-to-point links. PPP

defines an extensible Link Control Protocol, and proposes a family of

Network Control Protocols for establishing and configuring different

network-layer protocols.

This document defines the Network Control Protocol for establishing

and configuring Remote Bridging for PPP links.

This document obsoletes RFC 1638, which was based on the IEEE

802.1D-1993 MAC Bridge[3]. This document extends that specification

by including the IEEE 802.1D-1998 MAC Bridge[8] and IEEE 802.1Q

Virtual LAN (VLAN)[9] standards. This document also improves the

protocol in order to support high-speed switched LANs.
