I'm not sure if I understand. For now Neutron don't supports QinQ - old RFE is postponed currently [1]. And my original use case is related to the Neutron tenant networks which is Geneve type. How QinQ can help with that? > [1] https://bugs.launchpad.net/neutron/+bug/1705719 -- Slawek Kaplonski Senior software engineer Red Hat _______________________________________________ discuss mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
