Description

The regions that support CEN vary based on the network instance type. To query the regions where you can attach a specified type of network instances to CEN, set the ProductType parameter. If you do not set the ProductType parameter, the system queries all regions where you can attach network instances to CEN, regardless of the network instance type.
