A model describing the forwarding entries installed on a network element. It should be noted that this model is not expected to align 1:1 with the underlying structure used directly by a forwarding element (e.g., linecard), but rather provide an abstraction that can be consumed by an NMS to observe, and in some cases manipulate, the internal forwarding database in a simplified manner. Since the underlying model of the forwarding table is not expected to align with this model, the structure described herein is referred to as an Abstract Forwarding Table (AFT), rather than the FIB.
