Mike,
Thanks for the response.
I have tried both inside and outside the same subnet (intra vs inter
VLAN) on the one switch. Did not see any difference that is why I assume I
am not stressing the equipment sufficiently to see the difference. Can you
recommend a scenerio that would
Jason,
the real answer to your questions is this.
first why do we use layer 3 devices..
well MAINLY for intervlan routing,,,we are all agreed...yes
then ,
we migh have these two different setup`s. a 6500 with an internal MSFC
on a sup 2G...
and
a 6500 with an external router

If you look at the newest Cisco announcements, its
clear that the GSR and 6500 technology will replace
the legacy 75xx and other high-end router platforms.
These systems, depending on firmware, will use
hardware based CEF, which will negate the MLS flow

A layer 3 switch, as a previous poster said, is a switch, that has a route
processor (or that can connect to an external router), to perform Layer 3
functions at wire speed. But it also has ASICs that performs other
