Example setting up PPPoE

Overview

PPPoE is a network protocol for encapsulating PPP frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISPs IP network, and from there to the rest of the Internet.
