Hi
I was told that layer 3 switches are faster because "routing" there is
done by some ASIC hardware. Is there any advantage in having another
routing code in bridging when everything is done in software which is
same slow as normal routing? The only speed gain would be in keeping the
routing code very simple with limited functionality, but i think that
the trend is to put there more and more functionality which would end up
in having two same slow, same function code in two places.
(i was taugth that packets are routed on L3, frames are
switched(bridged) on L2. And L3 switch does L2 switching + L3 routing
but in hardware. routers are completely a software thing, switches
hardware thing, and bridge is switch in software.)
Please excuse me if i am missing your idea completely.

Is it even possible or even worth while to do layer 3 switching

Or would this be considered routing even though everything is done on
OSI Layer 2?
Which would be faster, Layer 3 switching (bridging) on OSI Layer 2 or
routing on OSI Layer 3?
