Explanation:
Before a routing table is used, the destination cache is checked for an entry matching the destination address in the packet being forwarded. If the destination cache does not contain an entry for the destination address, the routing table is used to determine:
The next-hop address - For a direct delivery (in which the destination is on a local link), the next-hop address is the destination address in the packet. For an indirect delivery (in which the destination is not on a local link), the next-hop address is the address of a router.
The next-hop interface - The interface identifies the physical or logical interface that is used to forward the packet either to its destination or to the next router.
