PPPoE Overview PPPoE

iMG/RG Software Reference Manual (ADSL Port)

The PPPoE client sends out a PADI packet to the broadcast address. This packet can also populate the "service-

name" field if a service name has been entered on the dial-up networking properties of the PPPoE broadband

connection. If a service name has not been entered, this field cannot be populated.

The PPPoE Active Discovery Offer (PADO) packet:

The PPPoE server, or Access Concentrator, should respond to the PADI with a PADO if the Access Concentra-

tor is able to service the "service-name" field that had been listed in the PADI packet. If no "service-name" field

had been listed, the Access Concentrator should respond with a PADO packet that has the "service-name" field

populated with the service names that the Access Concentrator can service. The PADO packet is sent to the

unicast address of the PPPoE client.

The PPPoE Active Discovery Request (PADR) packet:

When a PADO packet is received, the PPPoE client responds with a PADR packet. This packet is sent to the uni-

cast address of the Access Concentrator. The client may receive multiple PADO packets, but the client

responds to the first valid PADO that the client received. If the initial PADI packet had a blank "service-name"

field filed, the client populates the "service-name" field of the PADR packet with the first service name that had

been returned in the PADO packet.

The PPPoE Active Discovery Session-confirmation (PADS) packet:

When the PADR is received, the Access Concentrator generates unique session identification (ID) for the

Point-to-Point Protocol (PPP) session and returns this ID to the PPPoE client in the PADS packet. This packet is

sent to the unicast address of the client.

When this process has completed, the client is aware of the address of the Access Concentrator and a session

ID has been established. At this point, a normal PPP session begins. This session can remain established until a

PPPoE Active Discovery Terminate (PADT) packet is sent. The PADT may be sent by either the Access Concen-

trator or the PPPoE client.
