Configuring PADN Messages

You can configure PPPoE to receive PPPoE Active Discovery Network (PADN)
messages. When a client connects to a PPPoE server, such as an E Series router, the
client receives configuration information from the server via the PADN message.
This PADN information associates the PPPoE sessions with a set of routes. The client
can use this set of routes to determine which session to use based on the destination
IP address.
The PADN packet data is relevant only when the PPP network layer is " up." To reach
an up state, PPP alerts PPPoE after the Network Control Protocol (NCP) completes
negotiation.
The routes of interest can be maintained on the router in domain maps.
NOTE: For information about domain mapping, see JUNOSe Broadband Access
Configuration Guide.

You may send up to a maximum of 16 PADNs per domain name.
