Shahram,

 Who said that ECMP will be achieved only by hashing labels
 or IP header? I think you are thinking IP ECMP methods
 (RFCs 2991 and 2992) to solve MPLS ECMP. You can do ECMP
 in what ever way a vendor likes - after all, it is for
 load balancing. You can still achieve simple label lookup at
 the core by using appropriate ECMP technique(s).
