My first experience with PBR was as a summer intern in the mid-1990s who inherited management of a large ATM network that had a big VPN-esque thing built entirely that way and with no documentation. It certainly felt evil at the time. ;)
I think really PBR violates this: <http://en.wikipedia.org/wiki/Principle_of_least_astonishment> I see ISP folks MOSTLY avoid PBR, because it does weird things that NOC/ops folks just plain don't expect. I see Enterprise network folks fall back to PBR often, for reasons that they seem happy with... but man it makes things confusing :) -chris
