Spoofer Report for NLNOG for Aug 2024
by CAIDA Spoofer Project 08 Sep '24

08 Sep '24

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within nld. Inferred improvements during Aug 2024: none inferred Source Address Validation issues inferred during Aug 2024: ASN Name First-Spoofed Last-Spoofed 8587 Infracom 2019-10-28 2024-08-19 34465 SPV 2022-07-29 2024-08-28 207176 OPENFIBER 2022-09-30 2024-08-29 3920 IMS-RTFM 2023-10-06 2024-08-22 62353 ASN-DATAPLACE 2023-12-12 2024-08-21 215845 2024-01-02 2024-08-29 216455 2024-07-15 2024-08-23 Further information for these tests where we received spoofed packets is available at: https://spoofer.caida.org/recent_tests.php?country_include=nld&no_block=1 Please send any feedback or suggestions to spoofer-info(a)caida.org

Survey on the configuration of BGP routers
by Thomas Wirtgen 02 Sep '24

02 Sep '24

Dear NLNOG community, Apologies if you received multiple copies of this email. As part of my research into improving the configuration of BGP routers, I have created a survey for network operators. It will help to understand the processes you use to configure BGP and the challenges you face when configuring BGP sessions. Your expertise and experience will help us to develop new frameworks for configuring BGP sessions. I would be grateful if you could take a few minutes to complete the survey. Your participation will help develop solutions for network operators. https://forms.gle/hUwGJBaE9g72LQbQ6 I will announce the results of the survey on the mailing list where it was posted. Thank you for your time and your input, Thomas Wirtgen

draft-ietf-grow-yang-bgp-communities support in the NLNOG Looking Glass
by Teun Vink 18 Jul '24

18 Jul '24

Hi all, Some time ago Martin Pels proposed a standard for describing BGP communities in a standardised format. The draft can be found here: https://datatracker.ietf.org/doc/draft-ietf-grow-yang-bgp-communities/. This standard provides a formal definition of the way communities are used within an ASN. This allows for both automated generation of the definitions, as well as for the automated parsing of it. As you may know, The NLNOG Looking Glass tries to provide information on communities when looking up prefixes. We have used a custom, loosely defined format for that for a long time, and many of you have provided community definitions for their networks. Now, the NLNOG Looking Glass also allows you to host your own draft-ietf-grow-yang-bgp-communities style definitions. We can retrieve this file from a specified location and use it for adding BGP community details to the Looking Glass output. RIPE NCC was the first to provide definitions for their ASNs 25152 and 197000, so if you look up routes originating from those ASNs you will see community descriptions based on this standard. One of these prefixes is 193.0.9.0/24, a stored output with a number of different communities on it can be found here: https://lg.ring.nlnog.net/prefix?saved=KSSIRWOFx3 We hope this encourages you to formalise your BGP communities in a similar manner using this standard. Pull requests on https://github.com/NLNOG/lg.ring.nlnog.net/blob/main/community_urls.yml for new locations of definitions are welcome, and of course new files in the old format are also still appreciated. Martin, thanks for the great work and for the help getting this implemented in the NLNOG Looking Glass! Cheers, Teun PS: sorry if you received this email via more than one mailing list :)
