To be fair, Router Requirements (RFC 1812) required directed broadcast
be on by default. RFC 2644/BCP 34 was only published in August 1999,
changing the requirement to be OFF by default.

Some router vendors, notably Cisco and Proteon (a.k.a. OpenROUTE, now
NxNetworks) made the change prior to that new BCP, recognizing that
melting down the Internet was the logical result of leaving directed
broadcast turned on.

The gear I recently installed was a MAX 6000, running software rev.
7.0.3. I suggest folks give consideration to upgrading to versions which
support these features.
