A router receives an incoming packet and determines that the packet should be forwarded to a remote destination host. What will the router do to forward the packet?

When a router receives an incoming packet that needs to be forwarded to a remote destination host, it follows these steps:

1. Packet Arrival: The router receives the packet from an incoming link.

2. Destination Address Analysis: The router examines the destination address of the packet. This is usually the IP address of the destination host.

3. Routing Table Lookup: The router checks its routing table to determine the best path to forward the packet. The routing table contains information about the network topology and the most efficient paths to various network destinations.

4. Packet Forwarding: Once the best path is determined, the router forwards the packet to the next router along this path. This process is repeated at each router along the path until the packet reaches its destination.

5. If the destination is directly connected to the router (i.e., on the same local network), the router will forward the packet directly to the destination host.

6. If the destination is not directly connected, the router will forward the packet to another router that is closer to the destination host. This process is known as "hopping".

7. The process continues until the packet reaches its destination.
