Ack, thanks. Perhaps I misunderstood intent of actually dropping in flight traffic on switch fabric - this makes more sense and lessens my concern. Still think we should get IRR filtering in place first.

I'm still not understanding the difference between someone originating 8.8.8.0/24 and 8.8.8.8/32+65535:666. In either case (with blackholing support added), the route server will accept and propagate that to route server users.

I agree, that’s true in the current scenario. Nothing preventing you from doing that towards the route servers. As it stands right now, though, we wouldn’t necessarily have to accept that route, and we’d have local control to reject/block or filter your ASN, drop RPKI invalid prefixes, etc, and to react as we please (ie: operational processes to fix the issue without reliance on MICE intervention, and without completely dropping our route server sessions). Or perhaps folks are already doing self-generated prefix lists and actions towards route server prefixes already (we, for example, passively keep an eye on ASNs/IRR data vs routes learned from MICE route servers). In short, we’ve got tools to deal, if you do. > I agree that the IRR filtering is important, but is that absolutely > necessary here? In the case we enable a RTBH community without strict filtering, we’ve taken the control out of the members hands, and put a powerful tool in any members hands with no regard to security. Say someone does do something nefarious, or inadvertent that breaks something important? How quickly can it be fixed, who can fix it, etc, etc? Operational processes become a lot more important. The fix on a members side is a lot more intrusive (ie: turn down port), and the impact is much greater (blackholed across entire IX fabric - and potentially also affecting bilateral peering traffic). I think it’d be extremely irresponsible of MICE, and I’m vehemently opposed to enabling RTBH on the route servers or fabric, without first having the proper tools in place to ensure it can be used sanely and securely (IRR based filtering + route server looking glass).
