The Cidr Report

09 Feb '01

This is an auto-generated mail on Fri Feb 9 12:00:00 PST 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. 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

Migration issues: route creation
by Andrei Robachevsky 05 Feb '01

05 Feb '01

Dear Colleagues, You may know that the new version of the RIPE database (v3.0) also supports Routing Policy Security System (RFC2725). One of the implications is that this may prevent registrations of "foreign" routes in the RIPE IRR (that is routes from non RIPE address space and/or non RIPE ASN). According to RFC2725, creation of a route object should be authorized by the "owner" of the respective address space or aggregate route and by the "owner" of the ASN that is specified as route origin. In case of absence of the corresponding objects, creation of the route object will fail. The creation of the corresponding "foreign" objects will not be as easy in the new version as it is in the current one. The ASN space will be protected by as-block object, and IP address space by corresponding top level inetnum object. This makes registration of "foreign" routes almost impossible, which affects current practice when an IPS requests that clients' routes should be registered in the RIPE IRR. Possible solutions to this problem are: 1. Send such registration requests to the Database Administration (ripe-dbm) who will perform registration by overriding security (and performing necessary checks before). This puts additional load on ripe-dbm and creates duplicate objects in the RIPE database and "foreign" IRR. 2. Do not allow such registrations. In this case some ISPs will need to change their peering policy and accept routing information from a "foreign" IRR. Your comments and suggestions are highly appreciated. Regards, Andrei Robachevsky DB Group Manager RIPE NCC

The Cidr Report
by Tony Bates 26 Jan '01

26 Jan '01

This is an auto-generated mail on Fri Jan 26 12:00:00 PST 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. 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.

Weekly Routing Table report
by Philip Smith 22 Jan '01

22 Jan '01

Hi, Following several requests from participants in the European Operators Forum in Amsterdam today, I've decided to merge the reports I send separately to each region. Rather than posting the AP specific report to the APOPS list, the European specific report to the RIPE Routing WG list, and the American specific report to the ARIN RTMA list, I've combined each report into one posting sent to each of the three lists. Apologies in advance if this breaks any automatic mail filters - the new weekly posting will come with a subject line of "Weekly Routing Table Report"... I appreciate any comments or feedback you may have. I hope this change is an improvement, and will give all of you a better view of what is happening in each of the three registry regions of the world. best wishes! philip --

The Cidr Report
by Tony Bates 19 Jan '01

19 Jan '01

This is an auto-generated mail on Fri Jan 19 12:00:00 PST 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. 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.
