ASR9K cef load-balancing with ISIS

Can you anybody explain how to load balancing with CEF running ISIS/BGP MPLS? 

cef load-balancing ?

algorithm hash algorithm
fields hash fields

CEF has built in load-balancing, you should only really change the cef load-balancing at the direction of TAC after a thorough investigation of a load-balancing issue due to polarization as it changes the load balancing for the entire router.
