A while back, networks peering with the RSng route servers had access to the
PAIR reports which listed inconsistant and unregistered or policy-violated
(as per the IRR) routing anniouncements. Quite a few people claimed they
used PAIR to clean up their announcements and their registry objects. I
don't know if there were any agreement ramifications however.
AH> Bottom line, this inconsistency issue is not significant.
Agreed... even with strict policy checking. Amongst all the peering points
that the route servers were installed, inconsistant announcements accounted
for very little (most list of violations would fit in a single browser
window without having to scroll) with the occasional exception of
misconfiguration or massive policy changes in the IRR. We're talking
typically a maximum of a dozen inconsistancies and red-flagged routes
overall... usually for a small prefix.
