Vlan with HP Procurve

[KyleWood]

I have a Sonicwall Router with a subinterface vlan tag 20.  It has it's on subnet and it's on dhcp/route to the internet.  It then connects to a 24 port HP Procurve.  Plugged into that procurve is 2 more 24 port switches and a 48 port switch. 

As long as I tag the switch to switch port and swith to wap ports, will I need to do any layer 3 routing on the switches? Or will it all be kept on layer 2 and pushed out the sonicwall subinterface without a problem?

It will depends upon your edge devices gateway.

If your devices uses a default gateway configured on your SonicWall (the router have L3 interfaces to the subnets you mentioned) or in another device after the SonicWall, you don't need to setup L3 on these switches since it already have a default route pointing to the Sonic Wall router.
