If there is time delay between editing intended and the applied config matching the edits of intended, then I supose this can happen (I delete a resource from intended but it is still around until intended has been fully synced). I would find it interesting if some edits are always assumed to be synchronous but others may be asynchronous. And Lada, I think applied may happen to be never identical to intended if, for example, hardware is absent or other missing resources prevent certain parts of intended to become applied. My understanding is that applied config in general forms an extended subset of intended config. And to fully understand what a device is doing, I may need to obtain its entire operational state since the applied config may not include state obtained dynamically from other sources. But I might still all be wrong... /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 <http://www.jacobs-university.de/> _______________________________________________ netmod mailing list netmod@ietf.org https://www.ietf.org/mailman/listinfo/netmod
