Network operator discovers that measures taken to mitigate an old network security measure, long past their sell-by date, are now causing random grief. Seems to me like bang on topic for NANOG.
Agreed. Rare that people do haircuts on router configs; they're tedious and can not be delegated to an intern or someone else who doesn't have historical context. I just cut a config by half by removing unused ACLs, and even that is fairly painful.
What other such temporary mitigating measures are still in place long after the danger has passed. (?)
It's been almost nine and a half years and was a short-lived problem, but I'll betcha that an announcement from AS 7007 will have reachability problems to a measurable fraction of the Internet. That would make a kind of cool experiment. Vinny, you listening? ---Rob
