I currently have a business network comprised of older but still fully working Layer 2 managed GigE switches. If I would like to have inter-vlan routing on this network (without having to setup a separate network router) would I have to upgrade all of the managed switches to Layer 3, or does having one (it would be the central/main switch in a star topology network) Layer 3 switch in the network allow for inter-vlan routing without having to purchase all new managed switches throughout the network?
Thanks,
