I'm not sure if it's the same thing, but I've had a few alerts from Renesys lately seeing a path to my AS via GLBX 3549 that shouldn't exist, as we only have connections with Level 3 3356. For example, Renesys reports "x 3549 33517" where it should only be able to see "x 3356 33517" or maybe "x 3549 3356 33517". (Due to Renesys policy, I can't know what x is) -- Chip Marshall <c...@2bithacker.net> http://2bithacker.net/
