The Cidr Report

This is an auto-generated mail on Fri Oct 13 12:00:01 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

PI routing
by Okan Cimen 06 Oct '00

06 Oct '00

Hi, We are an ISP in Turkey and one of our customer wants Provider Independent IP Classes. As far as I know, I can get new Classes from RIPE (not within the classes I have allocated) . But I do not know about the routing part. Do I have to assign our customer an AS number and announce their independent classes by that AS #? Or will it be routed to our AS number? I hope that makes my question clear. I appreciate your help Best regards Okan CIMEN ------------------------------------------------ RT.Net - Rumeli Telekom A.S.

Dual-homing
by Edgar Reinke 05 Oct '00

05 Oct '00

Dear Madame, dear Sir! Are there any RIPE documents available which describe address assignment strategies for Multi-homed customer (multi-homed to different ISPs): - Does those customers require PI address space? - Does RIPE assign the PI address space (is it a /19 CIDR block)? - If the customer has to use PA address space from ISP A, must ISP B announce prefixes in addition to his CIDR blocks (or is it optional for ISP B to comply with the wishes of his customer with respect to the stability of the global routing system) Regards Edgar Reinke ____________________________________________ Edgar Reinke ExperTeach GmbH Waldstrasse 92 63128 Dietzenbach E-Mail: edgar.reinke(a)experteach.de

Dual Homing - possible solution?
by Matthew Robinson 05 Oct '00

05 Oct '00

Myself and a colleague have been working on a way of providing dual homing (different providers) without the need for each customer to register an AS. We feel that the solution is far from a finished product but in theory it should work. I would like to share the solution with the community. Are people intrested in this? If so I'll find a bit of web space and put it up or mail it ito the list. Kind regards Matthew

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.
