Abstract: Techniques for symmetric routing in a software-defined wide area network (SDWAN) are disclosed herein. In some aspects, the techniques described herein relate to a method including: determining a first device group, wherein the first device group includes a first router associated with a branch tag and a second router associated with a hub tag; determining a second device group, wherein the second device group includes a third router associated with and a fourth router associated with the hub tag; transmitting a first route advertisement associated with a first route from the first router to the second router to the first router; transmitting a second route advertisement associated with a second route from the first router to the third router to the first router; and preventing transmission of a third route advertisement associated with a third route from the first router to the fourth router to the first router.
