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.
Doubly confusing if ascend hasnt made it defaultThe last time I installed a TNT it wasn't even an option. The last time I worked with any piece of Ascend gear (pipeline 85), the Forward Directed Broadcast option was set to yes by default. This may have changed since then.
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. -- ----------------------------------------------------------------- Daniel Senie dts () senie com Amaranth Networks Inc. http://www.amaranthnetworks.com
