information for the interface.
To establish a PPPoE session, first the Services
Router acting as a PPPoE client obtains the Ethernet
address of the PPPoE server or access concentrator,
and then the client and the server negotiate a unique
session ID. This process is refereed as PPPoE active
discovery and is made up of four steps: initiation,
offer, request, and session confirmation. The access
concentrator generates the session ID for session
confirmation and sends it to the PPPoE client in a
PPPoE Active Discovery Session-Confirmation (PADS)
packet.
