Is there a writeup (or does anybody recall) a large-scale BGP failure in
the early 90s, when one ventor was testing a feature to make routes less
preferred (AS prepending or doubling) which caused all gated based BGP
implementation to lock up?   Unfortunately the processing order was: parse
the test route, forward test route, and then lockup.  So the test route
successfully flooded the entire routing system before locking up all of the
NSFnet and many other networks.

I am looking for a more complete and accurate description of this event.

Thanks,
