Thanks Akes for your inputs. I have been monitoring all the table update using ovsdb-mon <https://github.com/amorenoz/ovsdb-mon> . I dont see any addition or deletion in MAC_binding table updates. I have been running this script overnight. There was no change in the count and the table entries. I am suspecting that I might have missed some configuration parameter. I am referring here <https://github.com/ovn-org/ovn/blob/branch-23.09/northd/aging.c#L116>
