PPPoE: PPP over Ethernet

  1. 1. PPPoE PPP over Ethernet
  2. 2. Introduction • PPPoE is configured as a point to point connection between two Ethernet ports. PPP over Ethernet (PPPoE) provides the ability to connect a network of hosts over a simple bridging access device to a remote Access Concentrator
  3. 3. PPPoE has two distinct stages • Discovery Stage • PPP Session Stage
  4. 4. HOST=cc:05:0e:88:00:00 Destination The Host sends the PADI packet DESTINATION_ADDR= Broadcast Address CODE field=0x09 SESSION_ID=0x0000 Discovery Stage The PPPoE Active Discovery Offer (PADO) packet DESTINATION_ADDR=Unicast Address of Host CODE field=0x07 SESSION_ID=0x0000 The PPPoE Active Discovery Request (PADR) packet DESTINATION_ADDR=Unicast Ethernet CODE field=0x19 SESSION_ID=0x000 The PPPoE Active Discovery Session-confirmation (PADS) packet Begin PPP Session CODE field=0x65 SESSION_ID=Unique Value Destination=ff:ff:ff:ff:ff:f Destination=ca:01:0e:8 06
