A router receives a packet from the Gigabit 0/0 interface and determines that the packet needs to be forwarded out the Gigabit 0/1 interface. What will the router do next?

Once the router has determined that the packet needs to be forwarded out the Gigabit 0/1 interface, it will perform the following steps:

1. Lookup: The router will look up the destination IP address in its routing table to determine the best path for the packet.

2. Decapsulation: The router will remove the header and trailer from the packet that was added by the Gigabit 0/0 interface.

3. Encapsulation: The router will add a new header and trailer to the packet that is appropriate for the Gigabit 0/1 interface. This new header will include the IP address of the Gigabit 0/1 interface as the source IP and the original destination IP.

4. Queue: The packet is then placed in a queue for the Gigabit 0/1 interface. The router will forward packets from this queue based on its scheduling algorithm.

5. Transmit: Finally, the router will transmit the packet out of the Gigabit 0/1 interface towards its destination.
