A router is a device that operates at OSI layer 3. Because network protocols exist at layer 3, routers are generally protocol specific. I’ve limited the discussion here to TCP/IP, but routers exist for other network protocols as well. A key difference between bridges/switches and routers is that routers actually modify the packets moving across them, typically by changing the layer 2 addresses in the packet and by decrementing the Time To Live (TTL) counter. The TTL counter is a fiel...
