Can anyone confirm routing instability and/or huge path leakage from C&W? I'm hearing reports of this and seeing general instability/loss, but the route servers aren't showing anything funny. Thanks, Tim

We were seeing some pretty massive leakage from C&W starting around 90 minutes ago. It *appears* to have ceased, but I don't have confirmation from them that the problem has been resolved at this time. Chris
Route-maps people... I hope this was just a man made error, and not the total lack of route filtering. a different chris -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of Christopher B.

Cable and Wireless has ticket number 406-49673 open on this. Apparently another carrier leaked a full table to them, and for unknown reasons their filters did not prevent it. Chris On Fri, Apr 06, 2001 at 03:21:28PM -0400, Chris Kleban wrote:

I'm at a client site who is multi-homed to Verio and C&W. With both links up, various networks in C&W's net are unreachable with the same configuration that yesterday worked perfectly. The only massaging of BGP announcements their doing is with recieved routes and nothing on what they're sending out. We've taken the fractional DS3 to C&W down and everything is working again. Maybe this would explain why it just quit working for some reason. -- Joseph W. Shaw, II Network Design and Computer Security Consultant CCNA
