Yes. The whole idea is to expose these potential differences instead of hiding them behind a curtain. > 2. What is the distinction between dynamic configuration protocols and > control-plane protocols? Good question. I believe this to be at the end implementation specific. The question I think really is whether a control-plane protocol interacts with the configuration management component or not. > 3. Shared <candidate> has known problems.

Anyway, we need a general model and not a model for specific aspects such as routing. Yes, there can be redundancy but there can also be semantic differences. The <operational-state> datastore tells me what is actually used (regardless of what has happened with the statically configured values). In other words, if I want to debug what my box is actually doing, looking at the <operational-state> datastore is probably a good idea. /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
