i suspect this will turn out to be a non-issue, even of the new provider routes the blocks and nac.net strictly obeys the requirements of the TRO. the blocks broken out of the aggregates are probably (i haven't looked) likely to be dropped by filters at many large providers, which will seriously limit their utility.
We're not talking about a /24 or longer prefix here. Based on the amount of ARIN space Pegasus has and claims they've made, I'd guess they must have somewhere in the neighborhood of a /16 worth of NAC space, probably in several blocks of /24 and shorter. So, how do your filters tell the difference between these broken out NAC routes through a new provider and "multihomed customer routes with the primary provider's connection down"? ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
