You can configure the action taken by the PPPoE underlying interface when it receives
a PADI packet that includes a zero-length (empty) service name tag. The empty service
is present by default in every PPPoE service name table.
To indicate that it can service the client request, the interface returns a PADO packet in
response to the PADI packet. By default, the interface immediately responds to the
request; this is the terminate action. Alternatively, you can configure the drop action to
ignore (drop) the PADI packet, or the delay action to set a delay between receipt of the
PADI packet and transmission of the PADO packet.
(Optional) To configure the action taken for the empty service in response to a PADI
packet from a PPPoE client:
• Specify the action.
[edit protocols pppoe service-name-tables table1]
user@host# set service empty drop
You can also accomplish the following optional tasks when you configure the empty
service:
• Specify the agent circuit identifier (ACI) and agent remote identifier (ARI) information
to determines the action taken by the PPPoE underlying interface when it receives a
PADI packet with matching ACI/ARI information.
• Specify a dynamic profile and routing instance with which the router instantiates a
dynamic PPPoE subscriber interface.
• Limit the number of active PPPoE sessions that the router can establish with the empty
•
service.
