Abstract: Embodiments provide techniques for optimizing paths in a network environment with a virtual network device that includes a first physical network device and a second physical network device, connected using a virtual network device layer link. Embodiments receive a first data packet belonging to a first data flow, at the first physical network device, from the second physical network device, over the virtual network device layer link. An adjacent network device from which the second physical network device received the first data packet is determined. Embodiments also determine one or more links connecting the first physical network device and the adjacent network device. A network message is transmitted to the adjacent network device, where the adjacent network device is configured to transmit subsequent data packets from the first data flow to the virtual network device, using only the determined one or more links, responsive to receiving the network message.
