This document proposes a SONiC mechanism to track route-object ACK producers
— the per-ASIC
swssinstances that program route objects — and toexpose a single chassis-wide bitmap of producers that are alive and able to
acknowledge route-programming requests.
Consumers in the data-plane stack (
orchagent, route aggregators, FRR shims,etc.) can use this bitmap to decide when an aggregate ACK has been received
from all expected producers, and to suppress phantom ACKs from producers
that are gone (card removed, NPU down, container restarting, etc.).
