Abstract
Selection of proper virtual routing and forwarding (VRF) tables is based on a logical interface that is not associated with a physical interface. The selected VRF table is used to perform an output interface lookup for outgoing packets. In one example, a router includes a plurality of network interfaces, and a processing unit configured to select a logical interface not associated with any of the plurality of network interfaces based on an association with a received packet of a virtual private network, select one of a plurality of VRF tables in which to perform an output interface lookup for the packet that corresponds to the selected logical interface, and determine one of the plurality of network interfaces from the one of the plurality of VRF tables based on a destination of the packet, wherein the determined one of the plurality of network interfaces is configured to forward the packet.
