I have some bad news for you, if you run 6704 :). Lowest possible
working number for storm-control is 0.34%. And this is WAY
too high to protect the control-plane from say L2 broadcast
of valid L3 IPv4 unicast to your router.
 There is no way to thoroughly protect yourself from this,
in this platform.
 Your best bet is, to apply aggressive storm-controls in
the L2 connected to the 6704.

Thanks,
