What action does a router take immediately after matching a destination IP address to a connected routing table entry?

• A. Forward the packet to a remote server
• B. Switch the packet to the directly connected interface
• C. Drop the packet if unrecognized
• D. Log the packet for security analysis

Answer: (B)

When a router successfully matches a destination IP address to an entry in its connected routing table, it proceeds to switch the packet to the directly connected interface associated with that entry. This process involves determining the outgoing interface based on the routing table, which contains information about where packets should be forwarded based on their destination IP addresses. The router operates on the principle of examining the routing table to find the best match for the destination address. Once the appropriate route is identified, the packet is encapsulated with the necessary data link layer information and forwarded out through the correct interface. This action ensures that the packet continues its journey towards its destination on the local network or reaches the next hop towards remote destinations. This forwarding mechanism is critical for the router's function as a traffic director, allowing it to facilitate communication between devices across networks effectively.
