NANOG Website Redesign Project
by Randy Epstein 03 Sep '12

03 Sep '12

Greetings NANOG community, NANOG is in the process of completely redeveloping its website (http://www.nanog.org) and is looking for feedback from the community and NANOG members. One of the primary goals of the redesign is to present a clean, yet functional and up to date website, improving delivery of information to NANOG members and sponsors, as well as providing attraction to potential new members and sponsors. Additionally, a mobile-compatible version of the website with access to the same up to date information that the full website offers is another goal of ours. We have a long list of features that have been discussed within the various Committee and Board meetings. We however, want to make sure we hear more from the community, as our goal is to serve your needs. If you have a wish list item (or items)?, or thoughts about what works well on current site and what we need to make sure to improve, please send your opinions to us. We've set up a special email address where you can directly contact the folks working on the website re-design project. The address is CommunityFeedback(a)nanog.org. We're hoping to launch the website prior to the new year, so the sooner you get those great ideas to us, the sooner we can move the project forward. Thank you, Randy Epstein Chairman, NANOG Communications Committee On behalf of the Website Redesign Team

Bird vs Quagga revisited
by Hank Nussbacher 02 Sep '12

02 Sep '12

Sorry to disrupt the bad cabling thread, but I'd like to revisit a thread from 2 years ago. I have read over the NANOG presentations: http://www.nanog.org/meetings/nanog48/presentations/Monday/Jasinska_RouteSe… http://www.nanog.org/meetings/nanog48/presentations/Monday/Filip_BIRD_final… as well as the NANOG thread: http://www.gossamer-threads.com/lists/nanog/users/123027 But have not found anything worthwhile on the matter over the past 2 years. Both Quagga and BIRD have developed since the comparison in 2010: http://savannah.nongnu.org/news/?group=quagga http://bird.network.cz/?o_news But has anyone performed a more recent comparsion? Does Quagga still suffer from performance issues vs BIRD? Has anyone performed an RFC conformance test to see who complies more strictly to all the various RFCs? If BIRD is so much better than Quagga why is there no instance at Oregon: http://www.routeviews.org/ I also notice that BSD Router Project supports both: http://bsdrp.net/bsdrp How well do the two coexist at the same time? Any migration issues going from Quagga to BIRD? Any feedback appreciated. We now take you back to cable wars :-) Thanks, Hank

Redundant Routes, BGP with MPLS provider
by Tribble, Wesley 01 Sep '12

01 Sep '12

Hello all, I am an Network Operator working in an Enterprise environment with offices all over the country(mostly connected via MPLS). We are currently working towards building a Disaster Recovery Site that will host some of our vendor routers and provide the capability to access these vendors from both our primary and backup data center locations. The routes(as advertised by the vendor's routers) will be the same at both locations. I would like to advertise the routes from multiple locations at the same time, rather than suppress the routes and advertise conditionally. What is the best method to Instruct the provider's network to prefer the Primary Data Center routes over the DR site? Keep in mind that I am only peering with the provider over BGP and I have no visibility to the underlying MPLS architecture or configuration. Although if you have specific questions about their architecture, I can work to get answers. Discussing in house, we have gone over a few different options: -Advertise specific routes from primary site and summary routes from the DR site. Most specific will always be chosen. -Prepend the routes from the DR site so that they will have a longer AS-path than the Primary location -Use Community Strings to influence local preference.(Still working to find out if Provider will pass our community strings) Just looking for some ideas and best practices. Any thoughts or insight would be much welcomed and appreciated. This is my first message on NANOG, so please be gentle. I apologize in advance if I have done something incorrectly.

I have troubles with orange-yellow-greenish colors. Red is fine, most of greens as well. Already 15 years within the industry, several different jobs. Nobody ever asked me, but I think I mentioned it to all potential employers during interviews. For some of them it was funny or even interesting but I don't think anybody considered it as my disadvantage. Despite in most cases I cannot tell amber LED from yellow or orange one, I don't think it affects my duties. Usually different colors have also different luminosity, so shortly you learn characteristics of different products, like that with Cisco amber is the "darker one". I have also seen blades with broken LED's that had all the colors but one (like 6704 port with green and no amber), so to be 100% sure one should always check the console. -- Grzegorz Janoszka

Finding "Name Servers" (not NS records) of domain name
by Anurag Bhatia 01 Sep '12

01 Sep '12

Hello everyone I was dealing with a case where there's a mismatch in nameserver of a domain (nameservers set at registrar) and NS record on the delegated servers. Now NS on delegated servers are good and I am trying to create list of domains using wrong nameservers at registrar. Now as you would be knowing if I do regular dig with ns, it provides NS records. However I was able to find nameservers by digging gTLD root for gTLD based domains. This works for .com/net/org etc but again fails for say .us, .in etc. I was wondering if there's an easy way to do it rather then running script on thousands of domain names again & again digging registry specific nameservers? May be does someone knows/runs any simple server which can be whois'ed for some basic regular output which can be printed. Regular whois output for domain names seems hard to parse. Thanks. -- Anurag Bhatia anuragbhatia.com Linkedin <http://in.linkedin.com/in/anuragbhatia21> | Twitter<https://twitter.com/anurag_bhatia>| Google+ <https://plus.google.com/118280168625121532854>
