Entropy Label and FAT PW Label in Advanced Forwarding Toolkit

Junos OS supports entropy labels and Flow Aware Transport for Psuedowires (FAT) labels. Entropy label and FAT label when configured on the label-switching routers (LSRs) and label edge routers (LEs) perform load-balancing of MPLS packets across equal-cost multipath (ECMP) paths or link aggregation groups (LAG) without the need for deep packet inspection of the payload.
