yes that is exactly what i wanted to clear up, as in a router. ie routing is just a decision, and the physical moving of the packet between the interfaces (based on the above decision) is called as switching. right ?
and in a "switch" the moving of frames between appropriate ports (based on MAC addresses) is called as switching. right ? hope i got it all correct !! --- PING wrote: > I am not sure if I understood the question > completely but > I think you are trying to distinguish the L3 > switching and > Routing? > > Routing and Switching are two different functions > taking place > within router.
