      I've been wondering this for a bit.

      If you have 2 layer 3 switches, and 2 VLANs, and you configure both switches to be aware of all VLANs (also assuming you don't have a master/slave switch setup), will each switch route between the VLANs themselves, or does all traffic have to go through one switch to route?

        That would depend on the design of the switches. But generally I would expect routing to happen on each switch as needed.

          I'm think Scott is correct. Since a Layer 3 switch provides routing, there should be no issues with VLAN1 communicating with VLAN2 on the same switch, even if they are plugged into each other. I would think the switch, being layer 3, would have a local static route so that inter-VLAN traffic could occur?

          That would make sense, even from a hypothetical approach - on a layer 3 switch, it really wouldn't make sense to forward traffic destined for a local device on a different VLAN to another device and then back. Of course, this is exactly how layer 2 switches have to do it, but you get my meaning!

            Yeah I figured this was how it worked.
            Thanks
