Recently Completed BGP Study on "Peerlock"/Defensive Filtering
by Tyler McDaniel 13 Aug '20

13 Aug '20

Hello! My colleagues and I at the University of Tennessee recently completed a study on the “Peerlock” route leak protection system ( https://archive.nanog.org/sites/default/files/Snijders_Everyday_Practical_B…) and related defensive filtering techniques. Specifically, we probed for evidence of these systems on the control plane and attempted to locate filtering sites. Additionally, we evaluated the system's effectiveness in simulation. The pre-print of this paper is available at: https://arxiv.org/abs/2006.06576. While this work was previously mentioned here by Job Snijders, we want to make an additional push for comments from network operators. Our experimental design and findings in Section 3 may be of some interest. Most importantly, if any of the Tier 1 networks could confirm or challenge our findings with respect to their filter placement, that would be enormously helpful! We realize that this information is often secret/under NDA, but providing some element of ground truth would assist us in correctly evaluating our work. Thank you!

RIPE Stat routing info
by Sergey Myasoedov 07 Aug '20

07 Aug '20

Hello, For the every IPv4/v6 network I'm checking, RIPE Stat gives me "announced": false result. I'm observing this since last hour or two. Is this the outage or output format change in the RIPE Stat? Thank you. -- Kind regards, Sergey Myasoedov
