<br>
I want to highlight two efforts that I believe will help reduce the<br>
number of erroneous route objects that exist in the various databases.<br>
<br>
effort 1) The RIPE Routing Working Group is working on a policy proposal<br>
that would give mandate to RIPE NCC to remove route objects from the<br>
RIPE-NONAUTH database that are in conflict with published RPKI ROAs. A<br>
tool to analyse some of the changes this would bring can be found here<br>
<a href="https://github.com/job/ripe-proposal-2018-06" rel="noreferrer" target="_blank">https://github.com/job/ripe-proposal-2018-06</a> and the full proposal can<br>
be read here: <a href="https://www.ripe.net/participate/policies/proposals/2018-06" rel="noreferrer" target="_blank">https://www.ripe.net/participate/policies/proposals/2018-06</a><br>
<br>
effort 2) NTT is working on extending the IRRd software (IRRd is the<br>
software that insecure DBs like RADB, NTTCOM, ALTDB, etc run) to<br>
incorporate the RPKI Origin Validation process into the IRR workflow.<br>
Similar to proposal 2018-06, the IRRd software can be modified to<br>
automatically delete IRR route objects that are in conflict with<br>
published RPKI ROAs. This means that the moment you create a ROA...<br>
GLOBALLY the conflicting route objects will be hidden or deleted. IRRd<br>
4's developement can be tracked via <a href="https://github.com/irrdnet/irrd4" rel="noreferrer" target="_blank">https://github.com/irrdnet/irrd4</a> - I<br>
hope that this specific feature will be available this year, in 2019!<br>
<br>
My recommendation to everyone is: create RPKI ROAs for your prefixes...<br>
and just wait a few months. Significant change is coming to the IRR<br>
ecosystem, it'll be much safer quite soon!<br>
<br>
Kind regards,<br>
<br>
Job<br>
