Subscriber Services: Dynamic interface sets in heterogeneous networks

PPP can dynamically create business subscriber interface sets based on the physical interface name and the outer VLAN tag, matching the $junos-svlan-interface-set-name predefined variable. The AAA process sends the set name to the RADIUS server in the Juniper Networks QoS-Set-Name VSA (26-130) in the Access-Request message. The server returns the VSA in the Access-Accept message only for business subscribers. RADIUS does not return the VSA for residential subscribers. The returned VSA is used to create a dynamic interface set for the business subscriber. Otherwise, a default dynamic interface is created.
