Abstract
The subject matter described herein includes methods, systems, and computer readable media for next hop scaling with link aggregation. According to one aspect of the subject matter described herein, a system for next hop scaling is provided. The system includes a packet forwarding device including a plurality of packet processors for performing next hop and link aggregation group (LAG) selection operations. Within this plurality of packet processors, ingress packet processors are configured to indicate, for received packets that have a next hop on a different packet processor, that an egress next hop selection operation is needed. Egress packet processors of the plurality of packet processors are configured to perform the egress next hop and member selection operations for the packets for which an egress next hop selection operation is indicated, wherein forwarding of the packets is limited to active LAG group members local to the egress packet processor.
