CCIE Routing and Switching (legacy) — Question 22

If you configure the set ip default next-hop command on a device and the device receives a packet whose destination is missing from the routing table, how does the device route the packet?

Answer options

• A. The packet is policy routed to the destination address table that is closest to the destination address in the packet.
• B. The packet is dropped.
• C. The packet is policy routed.
• D. The packet is forwarded using the normal routing table.

Correct answer: A

Explanation

The correct answer is A because when a default next-hop is set and the routing table lacks an entry for a specific destination, the device will use policy routing to determine the most appropriate route. Option B is incorrect since the packet is not simply dropped; it is processed according to the policy routing rules. Options C and D do not accurately describe the behavior when the destination is absent from the routing table.
