Label-switched path aggregation

Techniques are disclosed for aggregating label-switched paths (LPSs). One method for aggregating LSPs may include a first node comparing forwarding equivalence classes (FECs) associated with respective label-switched paths (LSPs). The first node identifies FECs that differ by a given number of bits,...

Zusammenfassung:	Techniques are disclosed for aggregating label-switched paths (LPSs). One method for aggregating LSPs may include a first node comparing forwarding equivalence classes (FECs) associated with respective label-switched paths (LSPs). The first node identifies FECs that differ by a given number of bits, such as one or two bits based on the comparison. The first node generates an aggregate FEC that masks out the differing bits, thereby reducing the number of LSPs. The first node transmits the aggregate FEC to an ingress node.
