Issues with Level3 in chicago?
by Nicholas R. Cappelletti 19 Mar '09

19 Mar '09

We just experienced some connection issues with outgoing traffic through Level3. Anyone with similar issues? I can provide some traceroutes if needed, but just wanted to see if anyone else had similar problems. --- Nick Cappelletti nick(a)switchtower.org

Seeking Connectivity in IRAQ
by Robert D. Scott 19 Mar '09

A unit within the University has need to get reliable network connectivity to Iraq, more specifically Baghdad. I was wondering if any nanogers have any recommendations and/or contacts with providers in the area. Wired or Wireless. Off-list is fine. TIA Robert D.

Leap second tonight
by Kevin Day 18 Mar '09

18 Mar '09

Just a reminder that there's a leap second tonight. Last time I watched for what happened on 01/01/2006, there was a little bit of chaos: http://markmail.org/message/cpoj3jw5onzhhjkr?q=%22kevin+day%22+leap+second+… I've been told that some of the causes of these problems are fixed on any reasonably recent ntp distribution, but just in case, you might wanna keep an eye out if you're seeing any weirdness. The worst damage I'd heard from anyone after that event was their clock being significantly off for several hours. -- Kevin

SUP720 vs. SUP32
by Bill Blackford 18 Mar '09

18 Mar '09

Anyone have any experience with SUP32? Please contact me off list. I'm trying to evaluate a lower-cost alternative to the 720-3bxl. I'm only pushing a few hundred megs of traffic, exchanging a few routes with less than 20 peers and don't see the need for a 720's worth of throughput in the near future. Can the 32 handle a full table? How does the MFSC2A compare to the MFSC3? V6 support? Thank you. -- Bill Blackford Senior Network Engineer my /home away from home

Re: Origin ASN seen vs Origin ASN in Whois Records Report?
by K. Sriram 18 Mar '09

18 Mar '09

Heather: This prior question from you (November 2008) was recently brought to our attention. Sorry about this delayed response, but we thought it would still be worthwhile to share pointers to some work that we are doing at NIST which relates closely to your question. Earlier Bill Woodcock provided you with a link where the actual discrepancies are listed. Our work at NIST focuses on the statistics of such anomalies, with the intention of: (A) generating score cards for accuracy/consistency of various registries, and (B) to glean the "good" data from what is available so that BGP robustness algorithms that rely on the data can work more effectively. We have done an analysis of registry information (RIRs, IRRs, RADB) and compared it with that from trace data (RIBs, update history) from RIPE-RIS and routeviews. We generate a variety of statistics on a per RIR basis (ARIN, RIPE, etc.) regarding whether announced {prefix, origin AS} pairs in updates correspond with those in the registries. We also report on whether the registered objects (NetHandle and AShandle in SWIP format and inetnum, aut-num, and route in RPSL format) appear self-consistent or not. We also looked at the NetHandles in ARIN that contain origin AS information, and have performed comparisons of those with what was historically seen in BGP updates for prefixes belonging to the ARIN region. A variety of results and discussion related to all this are presented in this set of slides: http://www.antd.nist.gov/bgp_security/publications/ARIN_NetHandle_OriginAS_… You may also look into a presentation we made in January at NANOG-45. There the focus was on BGP robustness algorithms that make combined use of filtered "good" data from registries as well as long-term trace data. http://www.nanog.org/meetings/nanog45/abstracts.php?pt=MTE5NSZuYW5vZzQ1&nm=… Here is a link for a detailed published paper related our NANOG-45 presentation: http://www.antd.nist.gov/pubs/NIST_BGP_Robustness.pdf (This paper was published in the Proceedings of DHS S&T CATCH 2009 conference.) Please let me know if you have any specific questions concerning the above. We are very interested in receiving feedback on how this work can be made more useful from the perspective of what ISP needs are. Sriram K. Sriram +1 301 975 3973 http://www.antd.nist.gov/~ksriram/ ----------------------------------------------------- >From nanog-bounces(a)nanog.org Wed Nov 19 19:14:58 2008 Date: Wed, 19 Nov 2008 19:16:43 -0500 From: Heather Schiller <heather.schiller(a)verizonbusiness.com> Subject: Origin ASN seen vs Origin ASN in Whois Records Report? To: gih(a)apnic.net, nanog <nanog(a)nanog.org>, info(a)BGPmon.net I don't know if a report like this already exists, but I haven't been able to find one. Can someone (CIDR Report? BGPMon? PCH?) offer a report that shows the discrepencies in Origin ASN according to the whois records, and routes in the [global/public] routing table? Publishing it on some regular interval would be even better. ARIN makes available a list of prefixes with OriginAS. I don't know if other RIR's do. ftp://ftp.arin.net/pub/originAS/ To be clear. I want a list of the prefixes where the actual origin ASN seen does not match the one in the whois record. Inconsistent Origin is fair game here. As a transit provider I'm interested in seeing what prefixes I am transiting for my customers that have this discrepancy, so something that shows the full path as part of the results would be most helpful. Thanks, --Heather
