Correct, The only way around this currently is to peer with both cogent and HE. If you have cogent, You can 6to4 w/BGP with HE. I would consider that just a patch for the problem. I would do it just for the reachablility.

Looks like we have different Global IPv6 tables? Or does Cogent just NOT peer IPv6 peer with anyone else! Dennis
