PPPOE
       Point-to-Point Protocol Over Ethernet [protocol] (ADSL, RFC 2516,
PPP, ethernet), "PPPoE"
       

Point-to-Point Protocol over Ethernet
PPPoE

    (PPPoE) The protocol defined in
   RFC 2516 that allows one or more computers to connect to the
   Internet via a shared modem.  The computers connect to the
   modem via a local area network such as Ethernet and the
   modem connects to an Internet Service Provider (ISP) via a
   serial connection such as PPP over ADSL.

   PPPoE provides each user with a connection that looks and
   behaves like a point-to-point dial-up connection even though
   they are actually sharing an Ethernet or wireless network.
   At the same time, the ISP only needs to provide a single
   Internet connection, with the same kind of accounting as for
   PPP.  Also, the IP address is only assigned when the PPPoE
   connection is open, allowing the dynamic reuse of IP addresses
   via DHCP.

   PPPoE works by encapsulating PPP frames in Ethernet
   frames.
