Our draft is similar with section 6.1 in RFC5715, the cost of changed link will be adjusted and advertised, maybe more than one time, this sequence will base on some pre-calculations. But in RFC 6976, each device should calculate the distance with the failue link, base on this distance, each device decide when the FIB will be updated.

Can you contrast this with RFC 6976? You include RFC 6976 in the Normative References but it is never referenced (this will show up if you run idnits).
