I happened to be in one of our 7505 routers this afternoon when POP -- all of a sudden most of the internet disappeared! I immediately thought it was me, but looked around and saw this AS7007 broadcasting MY routes! It wasn't for all of our network space -- We have several /18's here, and it seemed only the first /24 of each CIDR was affected. When I found a workstation at the end of the /18, we got the whois info for 7007 -- Florida Internet Exchange, and called them. They claimed to have a customer broadcasting some bad routing information and unplugged their router. A few moments later, the internet stabilized and I started seeing real routes. Correct me if I'm wrong, but: (1) We're going to read about this in EVERY computer magazine, newspaper and TV as "the end of the internet?" (2) Access lists by backbone providers *should* have prevented this. (3) Does or does not the RADB and other routing registries (MCI's, etc) prevent this? I bet this hole will be patched up real soon! Steve
