With the end of ANS as a seperate network, will there be any network pressure to keep any public routing registry up to date?
Yes.
* Several people still peer via the route servers * Several transits filter their customers by RADB or a private RADB which feeds the IRR.
Care to name names? With ANS being one of those filtering, and knowing they connect certain large sites (e.g. CNN), it was possible to determine incorrect or improperly pulled RADB data was the cause of connectivity failures. Connectivity failures can and do result when RADB records are not properly updated, which does happen from time to time. They also happened when records WERE properly updated, but the changes made were deemed "too radical" by the software translating the RADB entries into internal databases. Moving a portable prefix from one ASN to another qualified as "too radical" a change, despite it being a semi common occurrence. Having those who use routing registries clearly state this policy somewhere, and state exactly how and when they take the updates would save much aggravation on the part of many.
If you do either of the above, chaning a public IRR (once) is easier than changing n private databases. The alternative is no filtering. Hopefully natural selection will take its course on transits who do this on a regular basis.
If common and consistent tools and rules were used to build filters from a SINGLE public database, and if the database site listed contact information and test addresses for each network using the database, I think folks could live with that. -- ----------------------------------------------------------------- Daniel Senie dts@senie.com Amaranth Networks Inc. http://www.amaranthnetworks.com
