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.

host1(config-domain-map)# padn 20.2.0.0 255.255.0.0 11
