global-gateway.net.nz and possible MTU problems
by Scott Howard 03 Aug '07

03 Aug '07

We've got a client in Thailand who is having having trouble with traffic from a number of sites - all of which go through global-gateway.net.nz. Based on the symptoms I'm guessing it may be an MTU issue (along with the other end blocking ICMP) - anyone seen this with global-gateway.net.nz before? If anyone here is responsible for that network I'd appreciate it if you could contact me off-list. Thanks, Scott.

29 Peering Points
by Philip D'Ath 02 Aug '07

02 Aug '07

Just thinking about all these Telecom peering points. Assuming that Telecom allocate IP addresses as they are requested by incoming broadband connections, as opposed to by geographic peering point, then there will be no way to summarise addresses at these peering points. So this will imply that those ISP which do peer at these points will have to listen to a good 100k odd /32 announcements (at the larger peering points). I could easily see the routing table having to contain 200k to 300k additional /32 routes if you want to allow least cost routing to work its best. If there are redundant paths then this could increase a lot more. Then consider the case when a /32 appears to be from Dunedin, and then the next second it appears to be from Wellington (because the Dunedin broadband user lost their session, and a new Wellington use just acquired their dynamic IP address). Then consider all the places these routes could be redistributed to within different ISPs, and potentially outside of their own AS. Then consider [non telecom] peering points that only accept a /24 or bigger. Not that anything is wrong with asymmetric routing, but doing it almost to the customer edge is going to make solving connectivity issues much more difficult (I can access this web site, but not that web site ...). I can see a lot of potential for route flapping, and for frequent routing updates to occur. I can also see the potential for short term route loops occurring. I see route stability issues arising in NZ's future, or have I missed something?

Notification of NZRR Database changes

Dear Colleague, This is to notify you that some object(s) in NZRR database which you either maintain or are listed as to-be-notified have been added, deleted or changed. These objects are used to configure the various NZIX route servers (http://nzix.net/) so you can expect the relevant servers to be reloaded in the near future. The reloading of the servers is staggered over a period of time so that if you are peering with both servers at an exchange, you can maintain at least one BGP session at all times and consequently a full set of routes. --- PREVIOUS OBJECT: route-set: AS9560:RS-ROUTES:AS24324 descr: advertised to AS9560 by Kordia - AS24324 members: 124.157.64.0/19^19-29, 58.84.224.0/20^20-29, 202.56.32.0/20^20-29, 202.68.80.0/20^20-29, 202.20.0.0/21^21-29, 202.49.16.0/21^21-29, 202.49.128.0/21^21-29, 202.56.48.0/21^21-29, 202.137.240.0/21^21-29, 218.185.224.0/21^21-29, 202.27.88.0/23^23-29, 202.65.160.0/23^23-29, 203.110.28.0/23^23-29, 192.173.17.0/24^24-29, 202.21.130.0/24^24-29, 202.27.83.0/24^24-29, 202.27.90.0/24^24-29, 202.36.75.0/24^24-29, 202.36.137.0/24^24-29, 202.36.154.0/24^24-29, 202.36.173.0/24^24-29, 202.37.168.0/24^24-29, 202.37.197.0/24^24-29, 202.49.158.0/24^24-29, 202.49.183.0/24^24-29 admin-c: RPA1-NZRR tech-c: RPA1-NZRR notify: rpsl-admin(a)nzix.net notify: nznog(a)list.waikato.ac.nz notify: smc(a)kordia.co.nz mnt-by: MAINT-NZRR-NZ changed: rpsl-admin(a)nzix.net 20070713 source: NZRR REPLACED BY: route-set: AS9560:RS-ROUTES:AS24324 descr: advertised to AS9560 by Kordia - AS24324 members: 124.157.64.0/19^19-29, 58.84.224.0/20^20-29, 116.89.224.0/20^20-29, 202.56.32.0/20^20-29, 202.68.80.0/20^20-29, 203.144.32.0/20^20-29, 202.20.0.0/21^21-29, 202.49.16.0/21^21-29, 202.49.128.0/21^21-29, 202.56.48.0/21^21-29, 202.137.240.0/21^21-29, 218.185.224.0/21^21-29, 202.27.88.0/23^23-29, 202.65.160.0/23^23-29, 203.110.28.0/23^23-29, 192.173.17.0/24^24-29, 202.21.130.0/24^24-29, 202.27.83.0/24^24-29, 202.27.90.0/24^24-29, 202.36.75.0/24^24-29, 202.36.137.0/24^24-29, 202.36.154.0/24^24-29, 202.36.173.0/24^24-29, 202.37.168.0/24^24-29, 202.37.197.0/24^24-29, 202.49.158.0/24^24-29, 202.49.183.0/24^24-29 admin-c: RPA1-NZRR tech-c: RPA1-NZRR notify: rpsl-admin(a)nzix.net notify: nznog(a)list.waikato.ac.nz notify: smc(a)kordia.co.nz mnt-by: MAINT-NZRR-NZ changed: rpsl-admin(a)nzix.net 20070801 source: NZRR

Netlantis - Routing Table Geoanalysis
by Philippe Bourcier 29 Jul '07

29 Jul '07

Hi, Sorry for the cross-post. The Netlantis team (Pascal Gloor and me) is pleased to announce a new BGP routing tables visualization project. This project is called Routing Table Geoanalysis and aims at representing various statistics based on the analysis of a BGP routing table. The result of this analysis is a poster-size computer-generated image (12+ Megapixels) which you can easily print. Project's URL : http://rtg.netlantis.org/ The statistics for each routing table we analyse are : - The distribution across continents (or more precisely geo-political areas) of the total number of IP addresses announced - The number of IP addresses announced for 100 inhabitants of these areas - The number of routes, IP addresses and the average number of IP addresses per route - The main upstream AS's share in the routing table (in number of IP) and the geographic distribution of IP addresses announced through or by them - The distribution of AS path length by continent - The prefix size distribution The geo-political areas (I'm abusively calling continents) used for the statistics are : Africa, Asia, Central America, Europe, Middle-East, North America, Oceania and South America. When it's relevant, I also use the area World which is simply a way to display the average statistics for the whole routing table. The posters (and statistics) will be automatically updated every month. English not being my native language, I'll be happy if some people can help me fix or improve my wording and explanations so they can be better understood, especially on this page: http://rtg.netlantis.org/?info=rtg I'm thinking about adding a page on which you could automatically upload (via curl) your clogin -c "term len 0\rsh ip bgp" every month so that any AS could also be listed without the need to peer anywhere... tell me if you are interested by this feature. Thanks to routeviews for providing the routing tables and to our sponsors : IP-MAN, OVH and MaxMind. ps: If you want to sponsor Netlantis, we found a piece of hardware which might help us return in a short time to production, the thing is a DDRAM-based hard-disk (more details on my blog), contact me in private if you can help us get one. Sincerely, Philippe Bourcier web : http://sysctl.org/ blog : http://netlantis.blogspot.com
