Abstract
The present technology considers network devices that include forwarding tables having a number of next-hop entries (e.g., egress ports) where it is possible that the egress port utilization can be load balanced using WCMP groups. To implement a WCMP group, its members are assigned weights representing an amount of data flow to distribute over a plurality of links for a given destination. The members may be replicated in a forwarding table proportionally to their assigned weights. This disclosure provides systems and methods to reduce the number of forwarding table entries required when implementing a WCMP group.
