Some DSL providers require you to set up PPPoE tunneling for your site in order to run PPP over the providers' DSL lines and high-speed digital networks. For an overview of PPPoE, see Support for DSL Users Through PPPoE.
A PPPoE tunnel involves three participants: a consumer, a telephone company, and an ISP. You either configure PPPoE for consumers, such as PPPoE clients at your company or consumers in their homes, or you configure PPPoE on a server at an ISP.
This section contains planning information for running PPPoE on both clients and access servers. The following topics are covered:
Planning information for the PPPoE host and access server
Explanation of the PPPoE scenario that is introduced in Example of a Configuration for a PPPoE Tunnel
