Our primary use case is routing. We are currently in the process of implementing the FabricOS here pretty soon, which is their alternative to the standard, what's called XOS, ExtremeOS, which is a more traditional switching and routing model, very akin to Cisco with a similar command line structure. With the routing capabilities, you basically have a way to turn your entire infrastructure across multiple locations into what looks like essentially one large switch, so routing becomes efficient. You can let VLANs talk to each other and control anyway through access control list.
