It's just wording. "backbone connected interfaces" means "interior interfaces on which you run your IGP". For example: int POS1/0/0 description connection to another backbone location ip address foo bar isis circuit-type level-2-only isis metric 1 level-2 which I think is what Jared means. The terminology to explain the difference between that and actually putting a prefix into your IGP is a bit dense, so a shortcut probably was a reasonable idea. --:) Sean.
