This is an auto-generated mail on Fri Aug 25 12:00:00 PDT 2000 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. 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

As many of you know, Merit began a production RPSL service on 11/1/99. RIPE-181 and RPSL coexisted on our production server until 1/1/00; after that date, RIPE-181 updates were no longer accepted and only queries were available on the special RIPE-181 server. Merit will now complete the final stage of its transition to RPSL by decommissioning its RADB RIPE-181 server on Wednesday, August 23, between 5:00-8:00 A.M. EDT. Query activity has been extremely light on the RIPE-181 server and the remaining users have been notified by private email about the termination of this service. This change will not impact our production RPSL service. Please send your questions and comments to db-admin(a)radb.net. IRRd Team --Gerald Winters

Vorerhebung Bandbreitenerhoehung VIX - Router
by Vyskocil Martin 09 Aug '00

09 Aug '00

Hallo Gerhard! Gestern fand eine Besprechnung mit der Uni-Wien; VIX statt. Die notwendige Hardware wird von Hrn Saumwald (TA) koordiniert. Die Anbindung des Highway zum VIX wird von ATM auf "dark Fiber" umgeschalten werden. Am VIX beginnen diesen Freitag die vorarbeiten zu Freischaltung der entsprechenden Leitungen. Die Schaltung der Leitung wird von Hrn Weissensteiner (TA) koordiniert. Dadurch wird es notwendig ein 2tes 100MB Interface zum VIX-LAN zu aktivieren. Zur Realisierung wird vom VIX die Fast Ethernet Option des Catalyst angeboten. Konfiguration (bestehend): - Anbindung Highway: ATM 65 MB - Anbindung VIX-LAN: 100 MB Konfiguration (neu): - Anbindung Highway: "dark Fiber" 155 MB - Anbindung VIX-LAN: 2 * 100 MB Konfiguration (neu) Stufe 2 (langfristig) - Anbindung Highway: "dark Fiber" 2 * 155 MB fï¿½r Backup- loadsharing- - Anbindung VIX-LAN: 2 * 100 MB Wie besprochen bitte um Klï¿½rung, ob unsere VIX Routerkonfiguration die Fast Ethernet Funktion unterstï¿½tzt, sowie um Aktivierung (in Abstimmung mit VIX und Betrieb). lg Martin ---------------------------- Martin VYSKOCIL Telekom Austria AG Product- and Service Development Tel.: +43 1 79711 1625 FAX: +43 1 79711 1608 mailto:mvyskocil@highway.telekom.at

The Cidr Report
by Tony Bates 04 Aug '00

04 Aug '00

This is an auto-generated mail on Fri Aug 4 12:00:00 PDT 2000 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. 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 xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.
