Hi, The fake_extension is used only in unit tests to test the extension framework, i.e. : https://opendev.org/openstack/neutron/src/branch/master/neutron/tests/unit/plugins/ml2/drivers/ext_test.py#L37 If you would like to write an API extension check neutron-lib/api/definitions/ (and you can find the extensions "counterpart" under neutron/extensions in neutron repository) You can also check other Networking projects like networking-bgvpn, neutron-dynamic-routing to have examples of API extensions. If you have an extension under neutron/extensions and there's somebody who uses it (see [1]) you will see it is loaded in neutron servers logs (something like this: "Loaded extension: address-group") and you can find it in the output of openstack extension list --network [1]: https://opendev.org/openstack/neutron/src/branch/master/neutron/plugins/ml2/plugin.py#L200 Best wishes Lajos Katona Igor Zhukov <fsb4000 at yandex.ru> ezt írta (időpont: 2022. aug. 22., H, 19:41): > Hi all! > Sorry for a complete noob question but I can't figure it out 😿 > So if I want to add Fake ML2 extension what should I do? > I have neutron server installed and I have the file: > https://github.com/openstack/neutron/blob/master/neutron/tests/unit/plugins/ml2/extensions/fake_extension.py > How to configure neutron server, where should I put the file, should I > create another files?
