IIRC, Comcast uses "local-as 7922" path rewriting for all enterprise EDI customers running BGP off of regional CRANs, unless I'm mistaken. So if your regional CRAN is as7015 (for New England), even if your physical circuit and BGP session land on a local SUR in your area, you have to use remote-as 7922 to setup the session with Comcast ENS, regardless of the fact that actual peer's router is using as7015.
This totally makes sense, thanks for the explanation!
