Abstract
Systems, methods, apparatus and computer readable medium are disclosed for extending Virtual Routing and Forwarding (VRF) for a network. An example apparatus includes ports, memory and processing logic. The memory includes VRF routing tables corresponding to respective VRF domains. The memory may also include a list of media access control (MAC) addresses, wherein each MAC address in the list is linked to one of the respective VRF domains. The processing logic may be coupled to access the memory and coupled to the ports. The processing logic may be configured to receive an ingress packet at a port of the apparatus, identify a VRF domain that the ingress packet belongs to, process the ingress packet according to the VRF domain, and optionally generate an egress packet, by embedding/writing a MAC address in the egress packet that acts as a source identifier for the respective VRF domain.
