When a host application needs to send a packet to a destination on a different network, the host addresses the data link frame to the router, using the address of one of the router's interfaces. The router's network layer process examines the incoming packet's header to determine the destination network, and then references the routing table which associates networks to outgoing interfaces. The packet is encapsulated again in the data link frame that is appropriate for the selected interface, and queued for delivery to the next hop in the path. This process occurs each time that the packet is forwarded through another router. At the router that is connected to the destination host's network, the packet is encapsulated in the destination LAN's data link frame type and delivered to the destination host.
