What will a router do immediately after matching the destination IP address to a network in its routing table?

When a router matches the destination IP address of a packet to a network in its routing table, the next action it takes is to forward the packet out of the appropriate interface that connects to that network. This process involves determining which directly connected interface has access to the network associated with the matched destination IP address.

The router uses its routing table, which contains various routes and their corresponding interfaces. After identifying the correct network, the router looks for the specific exit interface that is responsible for delivering packets to that network. Once the interface is identified, the router encapsulates the packet in a new frame that is appropriate for the data link layer protocol used on that interface and sends it out to reach the intended destination.

This process is fundamental to how routers function, ensuring data is directed appropriately across interconnected networks. By managing traffic this way, routers facilitate communication within and between networks, contributing to efficient data transmission and network organization.
