Cluster Load Balancing for Spine is a feature designed to ensure optimal load balancing of flows used as part of GPU based cluster communication in a network that uses multiple links to connect a TOR router to a Spine router.. When this feature is enabled on a Spine, it monitors RoCE traffic coming from a TOR and applies optimal load balancing when forwarding the traffic to the next TOR router hosting the destination GPU server.

This feature adds streaming support for the BGP RIB OpenConfig model via gNMI. The current implementation supports streaming of locRib for IPv4 and IPv6 unicast address families.
