Hi

OK I'll bite...

Yes there is a difference. It gets a little convoluted, but there is a
difference.

L3 switching: Think of a L3 switch as a multi port router that operates at
wire speed. The 2948G-L3 is an example. It is just a 50 port Ethernet
router. So L3 switching is routing traffic at wire speeds. You could use one
of these to route between VLANs, or route between networks.

Inter-VLAN routing: This is a technique, technology that is only used to
route traffic from one VLAN to other VLAN(s). It generally takes place at
wire speeds inside a Cat switch with a L3 switch option, but is often see
with routers that do not work at wire speeds.

So the bottom line... think of a L3 switch as a device, and Inter-VLAN
routing as a technology.
