we are now providing a router Looking Glass service for general use. http://ampz-natlib.natlib.govt.nz/cgi-bin/mrlg-natlib.cgi With ping, trace, and BGP routing table data available, from a Wellington router connected to, and peering with WIX/CityLink and Telecom. Also provided are a few scripts which will pull the same BGP routing table data, diff the tables and store the files in an archive every hour, and then create and update hourly, daily, weekly and monthly reports. These routing table data files are available to view individually, or are down-loadable as a month or year to date tar.gz and tar.bz2 files and may be of use to network research organisations. Only data from 09/09/2004 is available right now, but four weeks worth will be added from a test server over the next week. The idea is to build up some N.Z. Domestic BGP routing tables data history, before the rumored de-peering changes mentioned previously on nznog to WIX and APE, which are due to happen on November 1st 2004 ? These scripts are free to download and use, but are only any use if you run BGP routers. You will then be able to collect your BGP routing table data, before it disappears?; and maybe share it with others on nznog. You can look at the various diff reports to see how your network(s) are being advertised, and see any changes that are taking place, and this may help with diagnosing routing problems. full details at http://ampz-natlib.natlib.govt.nz Adrian Smith National Library of New Zealand t
