Generally, to configure anything which is chassis related, we have used the local openvswitch table. Each ovn-controller would read that and configure accordingly. One example is - ovn-openflow-probe-interval. Can't we do something similar here ? I understand that this config needs to be done on each chassis, but if it is a one time thing, then perhaps it should not be a big concern. Does this approach work for you ?
