Abstract
Some embodiments of the invention provide a method for using route filtering to relay routes between members of hub router clusters in an SD-WAN to reduce redundant route notifications to route reflectors (RRs) that advertise routes to hub routers in multiple regions connected by the SD-WAN and multiple edge routers at sites across the multiple regions. The method is performed at a first hub router of a first cluster. From a first edge router at a first site in a first region, the method receives routes of the first edge router. The method distributes the routes of the first edge router to a particular RR directly connected to the first cluster. The method distributes, to each other hub router of the first cluster, the routes of the first edge router along with an identifier that indicates that the routes should not be redistributed to the particular RR.
