Suggested Answer:

+ PPPoE Active Discovery Initiation (PADI): The client initiates a session by broadcasting a PADI packet to the LAN to request a service.
+ PPPoE Active Discovery Offer (PADO): Any access concentrator that can provide the service requested by the client in the PADI packet replies with a PADO packet that contains its own name, the unicast address of the client, and the service requested. An access concentrator can also use the PADO packet to offer other services to the client.
+ PPPoE Active Discovery Request (PADR): From the PADOs it receives, the client selects one access concentrator based on its name or the services offered and sends it a PADR packet to indicate the service or services needed.
+ PPPoE Active Discovery Session-Confirmation (PADS): When the selected access concentrator receives the PADR packet, it accepts or rejects the PPPoE session: "" To accept the session, the access concentrator sends the client a PADS packet with a unique session ID for a PPPoE session and a service name that identifies the service under which it accepts the session. "" To reject the session, the access concentrator sends the client a PADS packet with a service name error and resets the session ID to zero.
+ After a session is established, the client or the access concentrator can send a PPPoE Active Discovery Termination (PADT) packet anytime to terminate the session. The PADT packet contains the destination address of the peer and the session ID of the session to be terminated. After this packet is sent, the session is closed to PPPoE traffic.
