I use Verizon DSL (in my location Verizon uses PPPoE). My modem is a Westell 6100 modem/router. ( I have no additional networking hardware.) My OS is Fedora 7 (Linux).
I would like to have a clearer understanding of which PPP functions are integrated in my modem.
When I used to use dial-up, PPPD ("PPP daemon") was running in Fedora. Now, with DSL, PPPD is not invoked. Fedora includes PPPoE software (from Roaring Penguin Software). But this software is not being invoked on my system.
PPPoE is running on my modem/router. Does the modem/router also run PPP? I've read that PPP consists of a number of major states: establishing, authenticating, networking, terminating, and dead. Is any or all of this functionality integrated into the modem/router?
- Is the ethernet cable between my NIC and modem carrying strictly ethernet frames, as if the PC were on a LAN with no Internet connection?
- Is the line between my modem and phone jack carrying PPPoEoA frames or just PPPoE frames?
- Is there an information source (e.g. website, article, book) that elaborates on this? The PPPoE RFC is of minimal help to me. It just illustrates how PPP frames are encapsulated in ethernet frames.
