A FEC filter is defined within the network device and qualified by incoming interface information that identifies source sites of the packets. A label distribution protocol (LDP) FEC is configured such that packets of the given FEC are associated with the FEC filter. The FEC identifies a destination site of the packets received by the router and is automatically combined with incoming interface information. In this way, packet flows may be filtered based on FECs of the packets. FEC filters may be further refined to operate at forwarding class granularity. The techniques allow accurate billing of packets traveling between specific source and destination sites regardless of the number of interfaces of the network device the packets utilize. In addition, the filtering can be used to provide anti-spoofing capabilities."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Filtering traffic based on associated forwarding equivalence classes","description":"Filters are selectively applied to packets depending on forwarding equivalence classes (FECs) of the packets.
