Virtual tenant networks are one of the best features of NEC ProgrammableFlow solution – you can build virtual layer-2 subnets (based on VLANs, edge ports or port/VLAN combos), connect them with a virtual router, and implement packet filters and traffic steering ... while treating the whole data center fabric as a single device.
Even better, the ingress edge switch performs all the operations you configure (ACLs, L2 lookup, L3 lookup, source/destination MAC rewrite), resulting in optimal end-to-end forwarding.
