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
