Abstract
Systems, methods, apparatus and computer readable medium is disclosed for extending the Virtual Routing and Forwarding (VRF) in the network using embedded source identifiers in the packets. An example apparatus may include ports, memory and processing logic. The memory may include VRF routing tables corresponding to respective VRF domains and a list of media access control (MAC) addresses, wherein each MAC address in the list is linked to one of the respective VRF routing tables. The processing logic may be configured to receive an ingress packet at a port, identify a matching MAC address in the list that matches a source identifier of the ingress packet, and process the ingress packet according to the respective VRF domain associated with the matching MAC address that matches the source identifier.
