Point-to-Point Protocol Over Ethernet (PPPoE)

This section describes implementing an end-to-end ADSL architecture using PPPoE. PPPoE has gained popularity around the world because it offers intelligent capabilities comparable in some aspects to Layer 3 functionality, such as security, while providing an easy migration from simple bridging, even using the same simple DSL modems in many cases.

It's important that you can identify the protocols used for PPPoE. As in the other sections of this chapter, you will see the advantages and disadvantages of PPPoE.

PPPoE Overview

PPPoE is its own protocol, not just PPP encapsulated in an Ethernet frame. In general, PPPoE has a few of PPPoA's attributes, such as security authentication, but it is much more ...
