Detailed explanation-1: -A primary function of a router is to determine the best path to use to send packets. To determine the best path, the router searches its routing table for a network address that matches the destination IP address of the packet.
Detailed explanation-2: -1) the title asks what a router would do if it received a packet and can not find the destination address in its routing table. If there is a default route then the router would forward the packet using the default route. If there is not a default then the router would return an unreachable to the source.
Detailed explanation-3: -The router uses the information in the IP header to decide whether and where to forward each received packet, and which network interface to use to send the packet. Most packets are forwarded based on the packet’s IP destination address, along with routing information held within the router in a routing table.
