Configuring the Action Taken When the Client Request Includes an Empty Service Name Tag
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.
