1. A system, comprising:
a processor configured to:
determine a first network appliance to configure to communicate with a second network appliance using a virtual link, wherein the virtual link comprises a layer three overlay point-to-point data link;configure an inner interface of the first network appliance to receive data from the first network appliance to be sent via the virtual link;encapsulate the received data by adding a virtual link-related tunnel header for each data packet;configure an outer interface of the first network appliance to send the encapsulated data via the virtual link;determine the second network appliance to configure to communicate with the first network appliance using the virtual link;configure an outer interface of the second network appliance to receive the encapsulated data sent from the first network appliance via the virtual link;decapsulate the received data by removing the virtual-link related tunnel header from each received data packet; andconfigure an inner interface of the first network appliance to send the decapsulated data to the second network appliance; and a memory coupled to the processor and configured to provide the processor with instructions.
