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?

  • It encapsulates the frame with a source IP address by using the specific IP address of the destination host.
  • It encapsulates the frame with a destination MAC address by using the specific MAC address of the destination host device.
  • It encapsulates the frame with the destination IP address by using the specific IP address configured on the interface of the next hop router.
  • It encapsulates the frame with the destination MAC address by using the MAC address of the interface of the next-hop router.
    Answers Explanation & Hints:

    A router contains a routing table of all locally connected networks and the interfaces that connect to them. The routing tables can also contain the routes that the router uses to reach remote networks. When a router determines that an incoming packet contains the destination host on a remote network, it encapsulates the frame to forward it towards to the next hop router. It uses the MAC address of the interface on the next hop router as the destination MAC address. The MAC address is obtained through ARP.
