Sounds like the cisco bug which has affected several different providers over the last month or so. A route (almost always a high-interest destination) doesn't get added to the forwarding table correctly.

Not true. The fact that none of my colleagues, the isp team, and I was contacted/involved seems to suggest these routers do not run Cisco IOS.

Probally true. I received a report from a third-party the routers in this particular outage were not Cisco's. The routers were another vendor brand. I did leave a voice mail message, and e-mail to Data Comm explaining I had been informed I misidentified the router vendor. But I haven't been able to confirm what really happened either through C&W customer service (what outage?) or the other router vendor (no comment). However, before cisco account teams start popping champaign corks, the problem I did note with Cisco IOS and CEF does exist, and has affected a number of major backbones off and on for several weeks. A rather rip-roaring discussion is continuing on the cisco-nsp mailing list as we speak about CEF issues. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation
