RE: Cogent 100M DIA in Denver

["Eric C. Miller" <eric () ericheather com>]

I'm in the middle of converting IPV4 to dualstack with Cogent. I was told that they don't have IPV6 in the edge in 
Tampa yet, so they are VLANing us to a core device to give us v6. So by dualstack, they must mean dualstack only from 
an OSI Layer 1 approach. Heartburn city.....

Robert, do you have any advice from working with their ipv6 stuff, yet?

We've had them since May 2008.  Recently upgraded from 100Mb to 250Mb. 
Had minor issues here and there (no outages to speak of).

I've had some IPv6 issues since moving the link to dual-stack a few months back, but we are not deploying IPv6 to 
end-users yet, so I'll let them slide on that.
