				<content:encoded><![CDATA[<p>I&#8217;m moving our flat network which covers a three-story building and about 450 users to a subnetted network. I would like to know about connecting data closet switches to the core with redundant links. Can I implement OSPF on the core and connecting switches and eliminate spanning tree? In this environment do I really need VLANs per subnet or can I just subnet? I&#8217;m starting with new Cisco 6509 switches running VSS. I&#8217;m using the new switch to route between subnets. All data closet switches and server switches will have redundant links back to the core.</p>
