Refer to the exhibit. What will Router1 do if it receives packets that are destined to network 172.16.4.0/24?
- forward the packets to the gateway of last resort
- drop the packets
- send the packets to network 0.0.0.0
- send the packets out interface GigabitEthernet 0/0
Explanation: In this example Router1 does not have a specific route to the172.16.4.0/24 network. Because the 172.16.4.0/24 network falls within the 172.16.0.0/18 summary network route to Null0, this route will be chosen. As a consequence, Router1 will drop the packets destined for the 172.16.4.0/24network. The reason for Router1 not using the default route is that the Null0 route has a longer matching network mask.
