Abstract
During authentication of an SDWAN tunnel, Intent ISAKMP packets authenticate the local SDWAN controller and the remote SDWAN controller with each other, wherein the ISAKMP packets include a notify payload. Configured link costs associated with at least two member paths at the remote SDWAN controller that have heterogeneous physical attributes from the notify payload of the ISAKMP packets are retrieved. The configured link-cost of the at least two member paths is reflective of link physical attributes. One of the at least two member paths is identified based on a lowest link-cost between the at least two member paths, for steering SDWAN network traffic.
