VLAN Question.

All, is it perfectly legit, to have a vlan 202 with an IP range of 10.3.11.x and a vlan 203 with an IP range of 10.3.10.x? does that work, does that still prevent broadcast traffic?

Re: VLAN Question.

Yes. It is valid.I assume that the mask is 24.You need routing only for inter vlan communication.

How do I do inter vlan communication routing?

Re: VLAN Question.

If you are using an L3 switch you need to create 2 SVIs.[int vlan 202 and vlan 203]Also assign ip addresses in 10.3.11.x range for vlan202 and 10.3.10.x for vlan203.

If you have an external router you need to create a trunk on switch side and sub interfaces on the router side.Each sub interface is assigned the address as per vlan assignment.

Hope this helps.Let me know if you need any links.
