Hello Marco. Now I don't have any idea. But in my opinion there is issue on me3600. I haven't any proof, but it is just my experience with ME series switches. If you can, check this theory. Connect gi2/7 on cat6500 to another box and try setup ospf with bfd in some another ospf process. You can do it for me3600 too. Thank you. I really have no other idea. Murat
