Explanation What does a router do with a packet received from one network and destined for another network? The router performs the following three major steps: Step 1. De-encapsulates the Layer 3 packet by removing the Layer 2 frame header and trailer. Step 2. Examines the destination IP address of the IP packet to find the best path in the routing table. Step 3. If the router finds a path to the destination, it encapsulates the Layer 3 packet into a new Layer 2 frame and forwards the frame out the exit interface.
