Yes for RIB dumps. For update dumps, you just won't see any updates from a 4-byte AS peer. For RIB dumps, the entire format changed, so you won't see anything with older versions. > sure you don't want people who download the RIS raw data and try to > parse it with route_btoa or old versions of libbgpdump to stop being > able to use the raw data files, right? I prefer not to, but IMHO, it was the best option here. The other option could be to dump only route entries with a 4-byte AS in the new format. But that would lead to a very very nasty quagga patch and people might be missing routes without knowing. > If this stuff did break, were the users warned with an appropriate email > to the ris-users mailing list?

One on Jan 11, one on Mar 15 with details of the new format, one on Mar 22 (also sent to routing-wg) to say that changes will be applied on Mar 27. cheers, -- Erik Romijn RIPE NCC jr. software engineer http://www.ripe.net/ Information Services dept.
