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

The Cidr Report
by Tony Bates 29 Sep '00

29 Sep '00

This is an auto-generated mail on Fri Sep 29 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

Karl, thank you for your notification regarding RIPE-210 flaws. We have already identified some other problems, have been discussing those issues during the last RIPE meeting and are working on an update of this document.

The Cidr Report
by Tony Bates 15 Sep '00

15 Sep '00

This is an auto-generated mail on Fri Sep 15 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.

DB RPSL migration task force
by kieber＠ga-telecom.net 15 Sep '00

15 Sep '00

Re, at RIPE37 we have agreed to put a task force in place to prepare for migration to the new RPSL database, and I'd like to take the opportunity and solicit for members to this task force. Purpose of this task force should be finding the bugs in the new code before it is put to real work. Please review the migration plan at http://www.ripe.net/ripencc/pub-services/db/reimp/new-transition-v3.ps We also want to raise awareness that the new database is actually in RPSL format, so there are some significant changes to RIPE-181 format. If you are using scripts to query or update the database its very likely you have to adapt those scripts and the task force would like to benefit from your experiences when playing with the new database and testing your tools. While RIPE NCC is using a test suite to test the new database the best test is having real users beat on it. Remember, you will have to live with the bugs the task force doesn't find. If you are interested in participating, please, get back to me and I'll have you added to the mailing list <reimp-mig-tf(a)ripe.net> -- Ulf Kieber email: kieber(a)ga-telecom.net Network Engineer voice: +49-69-299896-21 Global Access Telecommunications, Inc. fax : +49-69-299896-40 internet solutions for business www : www.ga-telecom.net
