A dynamic routing gateway (DRG) is a virtual router that provides a path for private network traffic between networks. You use it with other Networking Service components to create a connection to your on-premises network using Site-to-Site VPN or a connection that uses FastConnect. For more information, see Overview of the Networking Service.
To use any of the API operations, you must be authorized in an IAM policy. If you’re not authorized, talk to an administrator. If you’re an administrator who needs to write policies to give users access, see Getting Started with Policies.
