This is an auto-generated mail on Fri Sep 14 23:00:00 PDT 2001 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. Check http://www.employees.org/~tbates/cidr-report.html for a daily update of this report. NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for the regional version of this report. NEW: Check http://www.employees.org/~tbates/autnums.html for a complete list of autonomous system number to name mappings as used by the CIDR-Report. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to GX Networks for giving me access to their routing tables once a day.
