The document that should outline which autonomous system numbers can be used in BGP (Border Gateway Protocol) for network transport is the Interconnection Security Agreement. This agreement defines the technical and security requirements for connecting two networks, and it typically includes details about the routing configurations necessary for ensuring secure and efficient data transfer.

Within this context, specifying which autonomous system numbers are to be used is critical for managing routing policies, maintaining control over network traffic, and ensuring compliance with security protocols. The agreement therefore serves as a formal document specifying how the connected systems will communicate, including the restrictions and configurations necessary for BGP.

Other options, while important in their own contexts, do not specifically address BGP configurations and routing protocols. A Service Level Agreement focuses more on performance expectations and service quality rather than technical routing details. Network Access Control pertains to managing who has access to the network but does not include specifics on autonomous systems. A Data Processing Agreement primarily relates to the handling of personal data and compliance with regulations, rather than technical networking issues related to BGP.
