In a scenario, where enable_distributed_floating_ip is set to False (default behaviour), ovn-bgp-agent does not attempt to announce the FIP from the gateway node when it is expected to.
This happens due to acquiring `requested-chassis` field during filtering of watcher. So LogicalSwitchPortFIPCreateEvent class asks for chassis id:

Which returns the UUID of the compute node, rather then gateway chassis:

From other side, to be fair, `ovn-nbctl list Logical_Switch_Port b9c80bef-7962-4db3-8b31-c0c53c75f9c5` does not contain any information that would map such FIP to a gateway - it's only mapped to the compute/VM:
