Correct answer
C.
To verify load balancing after configuration, issue the command “show route forwarding-table destination” to get the list of unicast next hops. The unicast (ucst) next hops are listed following ulst (unilist) in the type field. The command is usually issued on transit routers in MPLS network.
If you do not see the ulst, that means that the load balancing is not working, that is to say there are no multiple next hops to balance the traffic, but if there are more than one next hops, then ulst must first show on the type field before the ucst’s are listed.
Final answer is C, ulst.
