Abstract

A method includes generating at a multi-tenant controller on a network a common shared secret for establishing a link between a first site and a second site, transmitting the shared secret to each of the first site and the second site over a secured channel, assigning a wall clock based start and end validity period for the shared secret, sending the shared secret with a future validity to allow secure link communication to continue if one or more elements in both sites cannot communicate with the multi-tenant controller and using a separate shared secret per link per VXWAN.
