Talked with Cogent IP Engineering today, was doing my own prepending in the meantime. I received a number of replies on and off list with quite a bit of conflicting info from Cogent doesn't support any communities other than do not announce to they support this or that to references of RIPE and RADb both of whom seem to have some outdated info. It turns out they do support a bunch of communities, including path prepending of one, two and three times which are what I was looking for, and for at least the US market, they're all in the customer user guide which I hadn't received; no I really didn't receive it not just didn't read it. :-) The person I spoke with was going to have someone update RADb with current information as what's there is about eight months old I think. I ended up having to clear the peer session hard but then my community was applied and is functioning as intended. Only thing missing that would be really nice would be something like Level 3 where you can selectively prepend to a specific peer AS of theirs. :-) But they were very responsive as soon as got in touch with the right group.
