Hello: The transition of this branch to EM was done 1,5 years ago [1]. During this time the maintenance of Train networking-ovn has continued. However, due to the lack of time and personal resources, we can't properly maintain it. That leads to problems like [1]. The ML2/OVN driver was successfully merged in the Neutron repository in Ussury. We continue the development and improvement of this ML2 mechanism driver. A patch to mark this branch as EOL will be pushed in two weeks. If you have any inconvenience, please let me know in this mail chain or in IRC (ralonsoh, #openstack-neutron channel). You can also contact any Neutron core reviewer in the IRC channel. Regards. [1]https://review.opendev.org/c/openstack/releases/+/790760 [2]https://bugs.launchpad.net/neutron/+bug/1997262
