Andrei, The existing ripe2rpsl tool will automatically translate "AS-" to "ASN-" for the aut-num object and I think "ASN-" is more meaningful than "AS_". Best Regards.

The Cidr Report
by Tony Bates 31 Mar '01

31 Mar '01

This is an auto-generated mail on Fri Mar 30 23:00:00 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

Another issue related to the migration
by Andrei Robachevsky 29 Mar '01

29 Mar '01

Dear Colleagues, [Apologies for duplicate messages] One issue related to RIPE-181 to RPSL migration escaped our attention and has not been discussed. It is related to reserved prefixes that cannot appear in object names according to RPSL specification (RFC2622) which says: "Names starting with certain prefixes are reserved for certain object types. Names starting with "as-" are reserved for as set names. Names starting with "rs-" are reserved for route set names. Names starting with "rtrs-" are reserved for router set names. Names starting with "fltr-" are reserved for filter set names. Names starting with "prng-" are reserved for peering set names." Unfortunately "as-name:" attribute is an object name in RPSL and we have 133 aut-num objects with as-name starting with reserved 'AS-' prefix. Our suggestion how to deal with these objects is: 1. Send a message to the maintainers of these objects asking them to change the name to avoid conflict with RPSL specification. 2. Give two-week notice period after which ripe-dbm will convert non compliant as-names using the following mapping: AS-ASNAME -> AS_ASNAME. This is more a "cosmetic" change as as-name is not even a lookup key in the RIPE Database. Your comments and suggestions are appreciated. Best regards, Andrei Robachevsky DB Group Manager RIPE NCC

The Cidr Report
by Tony Bates 21 Mar '01

This is an auto-generated mail on Fri Mar 16 23:00:00 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.
