Effectively this means that if your public IP gets smurfed, it's b/w

never use border router i/fs).

If you are paying per bit, you'll still pay for smurfs, but they'll have
to be 45Mb/s in size to cause any real damage. You'll probably find BGP
flapping up and down as your T1 saturates is more of a problem.

I believe the major point was that the smurfed traffic shouldnt be routed
at all outside of the provider that hasnt fixed their smurf-relays,
bringing down the impact on transit providers as well...?
