And, of course, no need to actually route anything. Sounds like an excellent thing to throw commodity (OK, probably rackmount, but still) PC hardware at (potentially in clusters, I haven't looked into what the memory/CPU load of sessions boil down to on recent versions of BGP-capable software that runs on such). -- *************************************************************************** Joel Aelwyn System Administrator - lightbearer.com [email protected] http://users.lightbearer.com/lucifer/ Attachment:
