NextHop represents for the next hop of routing table, and RelyNextHop for the actual next hop in FIB.
The routing table and FIB are different entities, with different functions. Route is for upper layer, and the output by Display ip routing command is the next hop in route adding, which is called the original next hop in routing table, although it may be not reachable. Route management module finds the direct next hop through iteration for the original next hop of the route, and adds it into FIB for forwarding. The original next hop is related to the iteration next hop.
