Packet Tracer Lab 1.5.1

This packet tracer revolved around cabling a network with routers, switches, and hosts. Once we setup the network according to the desired scenario, the router needs to encapsulate the packet into the data link frame of of the outgoing interface. The switching function is a process used by a router to accept a packet on one interface and forward it out on another. A key responsibility of the switching function is to encapsulate packets in the appropriate data link frame for the outgoing data link. Therefore layer 2 data link addresses must change at every hop as the packet is decapsulated and re-encapsulated in a frame in each router.
