[db-wg] NWI-5 Out of region ROUTE(6)/AUT-NUM objects implementation request

Deqr all,

RIPE NCC's understanding of the requested solution is in agreement with
my own understanding. The NCC has identified the requested changes as a
simplification which is always good news. The suggestion to deprecate
"mnt-routes:" is a good one, and should be followed.

Based on RIPE NCC's report, I support moving this NWI to the next phase
(implementation).

Kind regards,

Job

ps. I'd leave the 'clean up out-of-region AUT-NUMs' for a separate
discussion on how to handle that data. Combining datamodel changes and
governance of existing data in the same topic might distract.

This means these objects will be created immediately, and the ‘pending object creation’ that is currently in place can be removed. This will allow us to simplify the core whois code as well as provide users with an easier user interface to manage their ROUTE(6) objects and compare these objects to the actual announcements done in BGP - similar to the interface currently provided to manage ROAs.

We propose that the attribute is deprecated and removed from existing objects (of course with notification to the object holders). Finally, there will be no more need for the existence of out-of-region AUT-NUM objects in the RIPE database. We propose that these objects will be deleted.

If no source is defined we propose that both "source: RIPE" and “source: RIPE-NONAUTH” ROUTE(6) objects are returned. We expect that otherwise existing scripts used to generate filter lists will no longer see the out-of-region ROUTE(6) objects, and that this will lead to unacceptably large number of issues. Operators can opt-in to discarding objects that use “source: RIPE-NONAUTH” in these scripts, or modify them to use “--sources RIPE” explicitly.

That said, we know that there have been different opinions on the feasibility of this in the past, so we encourage the working group to discuss this.
