In your case you can either do ovn-sbctl show and see which chassis has claimed the chassis redirect port - "cr-lrp-95b381bb-8dd7-47ba-a673-6724e8163c12" or you can run ovn-sbctl list port_binding cr-lrp-95b381bb-8dd7-47ba-a673-6724e8163c12 Normally the gateway chassis with the highest priority will claim the cr-lrp-* port. To move over to another gateway chassis you need to adjust the priority accordingly. I think the neutron ml2ovn driver manages the priority. However you can definitely override the priority by running - ovn-nbctl lrp-set-gateway-chassis lrp-95b381bb-8dd7-47ba-a673-6724e8163c12 <chassis_name> <prirority> I'm not sure if the neutron ml2ovn driver would revert back your changes or not.
