Gateway Selection specifies the Dynamic or Static selection of Gateways. If Gateway Selection is not selected, the Gateway is selected dynamically and Gateways are chosen from the Gateway Pool.

The specific Gateway chosen depends on the flow type (Edge-to-Data Center, Edge-to-Edge, or Edge-to-Internet). Business Policy and Edge-to-Edge regional location can also influence Gateway selection.

At least two Gateways (and their associated secondary Gateway) should be defined in the pool so that the Gateway selection is most efficient. If Gateway Selection is selected, the Gateway is statically selected and you need to specify the Primary Gateway and, optionally, a Secondary Gateway. Use the Static option only for test/debug purposes because it specifies a specific Gateway that is used for all flow scenarios.
