my weak memory, it was due to a number of factors, some in the database update workflow, some in the uneven usage workflow, e.g. ans updating once, or was it twice, a week. but this just underscores the difference here o with sbgp, the assertion of the validity of asn A announcing prefix P to asn B is congruent with the bgp signaling itself, A merely signs the assertion in the bgp announcement. o with sobgp, the assertion is in an external database with issues such as - data correctness & completeness - data consistency - update frequency - granularity (bgp is per-prefix, and this is used by real folk to do traffic eng etc). consider the mess of keeping this up to date and correct in a super irr. - etc its the old simplicity vs complexity game yet again randy
