Abstract
A method, apparatus and computer program product for providing Virtual Routing and Forwarding (VRF) and gateway Media Access Controller (MAC) distribution is presented. At least one subnet associated with a Layer 2 Virtual Switching Network (L2VSN) is provided on a network device. A message is propagated to a distributed Datapath. Network devices install the message as a routable MAC address on the L2VSN for the Layer 3 Virtual Switching Network/Virtual Routing and Forwarding (L3VSN/VRF) associated with the message. Edge devices route packets on the L2VSN addressed to the gateway MAC address.
