In the world of IRR and RPKI, BGP route acceptance criteria is important to get right. DE-CIX has published a detailed flow chart documenting their acceptance criteria: https://www.de-cix.net/en/locations/frankfurt/route-server-guide But I don’t see a lot of operators publishing their criteria. I imagine there is a some sort of coalescing industry standard out there, but so far I can’t find it. Of the upstreams I use, just one publishes a flowchart. Another is basically refusing to explain anything other than they “use” IRR and RPKI, ad that RPKI is “good”. I assumed that everyone implementing RPKI validation, would skip IRR route object validation if the route is RPKI-valid. I assumed that everyone is doing this now, or would do this when they implement RPKI validation. But I spoke to an operator today, which still expects all routes to pass IRR as well (and while they perform RPKI-validation, they effectively do nothing with the result). To me, this seems like a different direction than most operators are going. Or is it? The most surprising thing in the DE-DIX flow chart, was that they check that the origin AS exists in the IRR as-set, before doing RPKI, and if the set existence fails, they reject the route. I don’t see a problem with this, as maintaining as-sets is easy, but it does prevent an eventual 100% RPKI future with no IRR at all. I also thought there may be an informational RFC on this, but I couldn’t find anything. Has there been anything published or any presentations given, on generally accepted BGP route acceptance criteria? Tom
