Comment 1 Andreas Karis 2020-05-03 14:57:47 UTC 
Same issue in OSP 16.0:

        if config.is_ovn_distributed_floating_ip():
            port = self._plugin.get_port(
                context, fip_db['floating_port_id'])
            columns['logical_port'] = floatingip['port_id']

            if self._nb_idl.lsp_get_up(floatingip['port_id']).execute():
                port_net = self._plugin.get_network(context,
                                                    port['network_id'])

            columns['external_ids'] = ext_ids
Comment 2 Jakub Libosvar 2020-06-11 08:58:11 UTC 
I originally wanted to fix networking-ovn to make traffic centralized even after the reboot [1] but I think this is actually a problem in configuration that will be fixed by bug 1766930.

Andreas, are you fine closing this BZ as a dup of 1766930 ?

Comment 3 Andreas Karis 2020-09-27 08:21:47 UTC 
Sorry for the long delay. https://bugzilla.redhat.com/show_bug.cgi?id=1789836 is closed. Shouldn't this bug be fixed then, too?

Closing EOL, OSP 16.0 has been retired as of Oct 27, 2020
