urpf - evil?
by Baldur Norddahl 30 Oct '20

30 Oct '20

Hello While working on my ACLs I noticed that I was successful in blocking some apparently spoofed IPv6 traffic. The destination was Facebook and the source was IPv6 range belonging to a mobile operator that sells 4G Wifi router based solutions. So thinking about how and why a few customers end up sending packets to our network with the wrong source, I came up with a theory (not validated): What if the customer connects his 4G Wifi router to one of the LAN ports of our CPE (or visa versa)? His computer would then pick up an IPv6 range from both ISPs along with two default routes. But only one default route would be used, and in this case that was apparently the default route going to our network. But still his computer might use the IPv6 address from the other ISP as source and therefore he ends up "spoofing" by sending that to us. We deliver the packets to Facebook and I assume Facebook will route the replies just fine through the other ISP. Now the thing is that my impression is that it actually works so long I do not actively block it with uRPF or ACLs on our edge. I have learned that spoofing is evil and I should be blocking this - but why am I sabotaging something that apparently is doing just fine at some customers? Regards, Baldur

bgp dampening and anycast networks (particularly cloudflare)
by David Hubbard 30 Oct '20

30 Oct '20

Hi all, was curious if anyone has found it necessary to alter their route dampening rules related to anycast networks, and Cloudflare especially? I’ve got a customer whose target web server has been going intermittently inaccessible from a very geographically distant Cloudflare location (AU), while no reports of issues from anywhere closer to the US. I’m seeing a bunch of their /24’s dampened on my side in several locations, and they appear to be networks that favor or are specific to AU, so I’m thinking that’s the issue. I’m going to whitelist their ASN, but perhaps I need to work on the policy to be more tolerant of flaps compared to years past with the increase in anycast use? Thanks, David

Does anyone here know any more about what crashed in the DE-CIX NYC exchange yesterday between approximately 11am and 1:30pm? Between those times I'm told the Nokia switching fabric locked up and ultimately rebooted.

Recommendation to update RPKI validators
by Job Snijders 29 Oct '20

29 Oct '20

Hi all, About eight months ago I discovered a number of issues in the validation procedure of most RPKI validator softwares (including the RIPE NCC Validator, Routinator, and OctoRPKI). The impact of improper verification of Manifests (and associated aspects of the X.509 system) in the RPKI can have rather dramatic effects in today's Internet routing landscape. When handling a manifest, make sure everything is accounted for! The mitigation guidance is at present is very simple: just make sure all deployed RPKI validators are updated to the latest version. Going forward I hope our industry as a whole will be able to respond faster to issues of this type. A write-up with examples and details is available here: http://sobornost.net/~job/manifest_handling_issue.txt Thank you to all involved who helped fix & progress this issue. Kind regards, Job
