1)The PPPoE Active Discovery Initiation (PADI) packet:
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
connectoid. If a service name has not been entered, this field cannot
be populated.
2) The PPPoE Active Discovery Offer (PADO) packet:
The PPPoE server, or Access Concentrator, should respond to the PADI
with a PADO if the Access Concentrator 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.
3) 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 unicast 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.
4) The PPPoE Active Discovery Session-confirmation (PADS) packet:
When the PADR is received, the Access Concentrator generates a 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.
