Abstract

A process can include determining affinity information indicative of route preferences between branch routers and gateway routers. A prefix can be determined for a subnet of branch routers located at a same branch location. An affinity position of a first gateway router can be determined based on affinity information of the branch routers in the subnet. A mapping can be determined between a local preference Border Gateway Protocol (BGP) community attribute and the affinity position of the first gateway router, wherein a mapped local preference BGP community attribute and the affinity position are indicative of a same routing preference. The mapped local preference BGP community attribute can be attached to routes from the first gateway router into a cloud service provider. Affinity-based route preferences are indicated to the cloud service provider by redistributing the routes from the first gateway router with the mapped local preference BGP community attribute attached.
