Re: Euro-IX quagga stable download and implementation
The best IX list I've found is Open-IX as it's the only one I've found dedicated to IXes while still being public. Tried to join the Euro-IX ones, but as you indicated... members only. - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com - Original Message - From: Andy Davidson a...@nosignal.org To: Goran Slavic gsla...@sox.rs Cc: nanog@nanog.org Sent: Friday, April 24, 2015 4:30:12 AM Subject: Re: Euro-IX quagga stable download and implementation Hi, Goran, everyone -- On 23 Apr 2015, at 09:06, Goran Slavic gsla...@sox.rs wrote: at the mailing list and have an interest in downloading and implementing the Euro-IX version of Quagga in our Internet exchange.

There are three well known open source BGP implementations which are commonly used as a route-server - BIRD, Quagga, and OpenBGPd.

Calculating best-path for every participant becomes complex when you have a lot of participants, further when the number of prefixes on the exchange grows. OpenBGPd will stay up but take a very long time to process and forward announce/withdraw BGP messages. On a ~100 ASN/participant/table system with ~5000 prefixes, it can take anywhere up to an hour for a withdraw to be processed and forwarded which means your participants will get a route that is withdrawn for a long time and blackhole traffic at the exchange. It is therefore problematic to use this software on all but the smallest exchanges. It’s OK on small instances but does not scale.

OT: Long term contract work in Boston/Cambridge area
Good morning, First, I beg your pardon if job posting are unacceptable. I had a quick glance at the website and didn't see anything jump out as prohibited. I've got a couple of contractor positions open in Infosec and am hoping to find someone with a good background in networking, tools (IDS, Flow collection reporting, Splunk, etc.) who is also decent at scripting (most stuff is in perl but python would be ok too). Positions report to me so I'll be able to answer any questions you might have. Cheers, Harry

Re: Euro-IX quagga stable download and implementation

[...] Quagga's vanilla build will fail to stay up with large numbers of tables and participants. Chris Hall did an amazing job at making a build that was more prone to staying up and his build is doing a sterling job at LINX (alongside BIRD) but I understand that this source tree is no longer maintained and that the task of merging his stability fixes into the mainline or OSR (https://www.opensourcerouting.org) version is not a simple job and has not been done. This gives me a serious concern about the future of this branch. On the Chris Hall branch: Chris did some great work fixing many issues, but unfortunatly, mostly in a solo mission on it's own. The idea (from the beginning when Euro-IX sponsored his work) was to get this integrated back into the mainline Quagga. However, by the time we got access to the code, it was a basically one large diff of 1000's of lines with no git history. This would be a lot of work to pick it apart again, review the code and commit it (in pieces) into the mainline. We talked about supporting it as an alternative BGP daemon, but he changed quite a bit in zebra as well, so this was still too much work. When I say too much, the issue was that noone was willing to sponsor the work (person or money) to get this integrated. We did (actually multiple times) look into the issues and made different plans on how to get the BGP performance fixed. But so far (in the past), everyone who sponsors us doesn't care much about the BGP scale and cares more on IPv6 with OSPFv3, ISIS etc. So that's where most of our work went. (Plus a lot of testing. I think Quagga is the only Open Source routing platform which is tested against protocol fuzzers and for RFC compliance) There is now (again) some interest (mainly form european IX'es) to look into the problems and we started (again) to evaluate, measure and see how we can fix it on a limited budget. The idea is to really get Quagga usable as a RouteServer to have a 2nd choice (beside Bird). Happy to get donations (We are a US 501c3 non-profit) to actually make it happen. Overall, if everyone here who complains would just donate a little bit money (or some work), then the whole issue would be long solved. BIRD just doesn?t die, no matter what scale we seem to throw at it. This thing just keeps flying. Short term, if you are ok with a single solution and need something now for a route-server, I think Bird is the solution. Long term, I hope to get Quagga as an alternative (and for everyone who wants 2 different solutions). Bird initially was (and still is) focused to the Route server Route reflector application and has some unique features there. Quagga is today more focused as a full routing daemon and mostly used in virtual routers, SDN applications and ToR routers. Regards, Martin Winter (OpenSourceRouting, NetDEF)
Fibre optic patch cables in Vancouver area

I'm not looking for information about suppliers who require more than 1 day to have ready, and don't allow local pickup. Thanks! - Miguel
