That doesn't scale particularly well. The time needed to 'sync' is still linear with respect to the number of prefixes, and you end up sending a digest of your database. When the items involved gigabit files, this is an efficiency win. When the routes are in the hundreds of bytes, you're saving maybe 2 orders of magnitude over the entire database. Sure, that's better, but that's a fixed, one time multiplier on scale. Sooner or later, you'll exhaust that. > Note that RPKI is rsync based which some suggest for BGP to relay on anyway ;) My recollection is that this was for static key information. Only slightly different. ;-) Tony _______________________________________________ GROW mailing list GROW@ietf.org https://www.ietf.org/mailman/listinfo/grow
