C – Asymmetric routing
At its most basic level, there can be a race condition between Load Sharing cluster members in which asymmetric return traffic for a new connection “outruns” the state sync update between cluster members. When an outrun occurs SDF ensures the packet is always handled by the same cluster member and not dropped.
