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. -- /*===================[ Jake Khuon <[email protected]> ]======================+ | Packet Plumber, Network Engineers /| / [~ [~ |) | | --------------- | | for Effective Bandwidth Utilisation / |/ [_ [_ |) |_| N E T W O R K S | +=========================================================================*/
