As he said, the problem is when interfaces get maxed.
Suppose someone coming in over your T1 smurfs the broadcast address of a
busy ethernet. Now you've got 1.5mb of incoming echo requests and as much
as 10mb worth of outgoing echo replies.
Its while your cisco does its best to deliver 10mb of traffic out a
saturated 1.5mb pipe that things can get problematic.
Of course, as has been mentioned elsewhere, this is fairly easy to
prevent. There isn't much reason for something outside to be sending
packets to an internal broadcast address, so just drop them.
