IGP routing protocol traffic is automatically marked with DSCP CS6 and is given high priority through an internal mechanism to ensure the neighbours stay up. You don't really have to do anything to make it high priority.
However, if you really want to try it, I would use class-based wfq and put CS6 in the priority queue, rather than using legacy priority queuing.
