Abstract
Systems and/or methods that facilitate the segmentation of layer 3 (L3) data to more than one virtual private network (VPN) or virtual network (vNET) are presented. An application classifier component can be used to facilitate the classification of L2 to and from hosts and/or other networking components that are attached to a network based on the type of application with which the network traffic is associated. The innovation associates multiple Virtual Local Area Networks (VLANs) with the same L2 forwarding table ahead of bridging into shadow VLANs (SVLANs) which can be associated with different L3 vNETs. The application classifier component can classify data traffic at the switch port through Switching Virtual Interfaces (SVIs) into SVLANs which can be associated with different L3 vNETs. Each vNET can be optimized and provide services specific to which type of application in which the vNET is associated.
