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.


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.

This document describes the PPP Over Ethernet encapsulation that is

being deployed by RedBack Networks, RouterWare, UUNET and others.

1. Introduction

Modern access technologies are faced with several conflicting goals.

It is desirable to connect multiple hosts at a remote site through

the same customer premise access device. It is also a goal to

provide access control and billing functionality in a manner similar

to dial-up services using PPP. In many access technologies, the most

cost effective method to attach multiple hosts to the customer

premise access device, is via Ethernet. In addition, it is desirable

to keep the cost of this device as low as possible while requiring

little or no configuration.

PPP over Ethernet (PPPoE) provides the ability to connect a network

of hosts over a simple bridging access device to a remote Access

Concentrator. With this model, each host utilizes it's own PPP stack

and the user ...
