hmmm......... in the aforementioned new Cisco CDs I just got there is a "8
Minute Layer III Switching QuickStudy".
The interesting thing it points out between differences in using a router to
route or a switch to "route" is that routers have RISC processors and
switches have ASICs.
It goes on to say that the RISC is more powerful and meant for doing other
things like encryption, handling WAN traffic, etc - whereas ASIC does
forwarding only. (but is much faster doing it)
So it comes down to your environment and the invariable "what problem are
you trying to solve" kind of thing.
