Re: Cogent leaking /32s?

I called cogent. Best guess is that they leaked the /32 announcements
that people do for the peer a/b stuff. They normally filter them, and
don't have any recommendation about whether or not to set no export.

I received an alert from Cyclops telling me a probe in AS513 had seen
a /32 that I announce to Cogent for one of our BGP sessions.

Did anyone else see this?

cyclops alerted me that the /32s my routers use got announced. I'm still
tying to figure out what's up. They're not routes I announce, and as far
as I can tell, they were announced with a cern next hop.
