The routers obtain the relation between the destination host’s protocol address and its physical address using the ARP request/reply mechanism.The information is stored within the ARP table in the router. See “The ARP Table“ on page 55.
Within an enterprise, routers serve as an internet backbone interconnecting all networks. This architecture strings several routers together by a
Another approach within an enterprise is the collapsed backbone. This uses a single router with a
