Configuring Pado Delay - Cisco ASR 9000 Series Configuration Manual

PPPoE Smart Server Selection
message to the BNG with which a session needs to be established. Most PPPoE clients send a PADR message
to the BNG from which it received the first PADO message. By configuring the Smart Server Selection feature
on BNG, a delay is added to the PADO messages sent from the BNG, based on the properties of the PADI
messages received from the PPPoE clients. This delay in receiving the PADO packets, in turn, gives the PPPoE
client the flexibility of effectively selecting the appropriate BNG to which the PADR message is to be sent.
Configuration options for Smart Server Selection
• Allows configuring a specific delay for the PADO message sent from BNG.
• Allows configuring a delay for the PADO message sent from BNG, based on the Circuit-ID, Remote-ID
• Allows Circuit-ID and Remote-ID tag matching, with strings up to 64 characters in length.
• Allows partial matching on Circuit-ID, Remote-ID, and Service-Name contained in the incoming PADI
