On Friday, I presented at the Netnod meeting in Stockholm, Sweden - again about BGP error handling - this time presenting a bit of an update as to why this continues to be a problem for the Internet (and private BGP deployments) - and why this work is still really relevant. In addition, I tried to give an overview of what the solution space looks like. I’m not sure whether there’s video, but as usual, the slides are linked below!

It's been quite a while since I updated this blog, very lax of me, sorry! The lack of updates appears more indicative of how busy I appear to have been since presenting the error handling draft work at NANOG (which looks to be the last post!). Since January, I've presented at the IETF in Prague, and then again in Qu�bec City - particularly on a number of aspects of the work that I've been documenting here for some time!

The video from the presentation I gave a NANOG, LINX and UKNOF has now been posted. You can find the video at the following URL - NANOG 51: BGP Error Handling or by clicking on the image below. The full slide deck is also on this site - here.

As I presented at UKNOF 18, I have now written an Internet-Draft to address the requirements of Network Operators for how BGP should handle errors in UPDATE messages. The draft can be found on the IETF site, and I'm currently seeking opinions as to whether this reflects the an operational consensus! If you're an Operator (DFZ, MSE or otherwise), it would be great to hear from you! I'll be presenting the draft at NANOG 51 in Miami on Tuesday - if you're there, feel free to ping me!

With IETF 79 happening last week - I think one of the great things that's coming out of the IDR work leading up to the meeting has been that quite a few drafts have been written around the requirements that exist in BGP for better error handling. I've been vocal about this before, of course, so it's not that surprising that I'm (yet again) banging the drum for this cause, however, we are getting somewhere finally.

Tom Bird of PortFast and Brandon Butterworth of Bogons do a great job of webcasting, and recording UKNOF video. Thanks to them, the video of the presentation I gave at UKNOF16 can be watched here. Or you can download it by clicking the image below! As always, thoughts/comments/corrections most welcome! This is also probably a good time to mention that my new work mail address is rob.shakir (at) cw.com

After a late programme committee request, I presented on “Enhancing BGP” at UKNOF 16. The presentation was intended to be an update on the current drafts in the IDR working group, and give some encouragement to operators to get involved, and contribute. I’ll put the video up when the Tom at PortFast and Brandon of Bogons have done their excellent job on it. For the meantime, the slides are linked below.

It looks like, once again, there's another attribute flying around the global BGP table causing Quagga instances to crash (if based on 0.99.9 - I believe the bug is fixed in 0.99.10). This relates to the 2007 draft that introduced AS_PATHLIMIT - see ietf.org - draft-ietf-idr-as-pathlimit. This attribute is actually relatively interesting, from an operator's point of view, where control that is more granular than setting the common no-export or no-advertise communities does not suffice.

I’ve had a couple of mails relating to this PSN, which again references the research that Andy Davidson, Jonathan Oddy and I did last year. It seems that some of the sources of the initial mailing list posts we made are gone (particularly the merit.edu one that is referenced from both Juniper’s site and most other places). For that reason, I’ve included both the mails that we sent to NANOG/C-NSP/J-NSP last year here.

Further to my previous post - I presented this issue at LINX65 - video and slides can be found below. Video Fixed Slides - LINX’s PowerPoint install seems to have corrupted my slides on the day. Comments and feedback are most welcome.
