Which programming model is vendor-agnostic and uses separate containers or models for operational and configuration data?

OpenConfig YANG models are specifically developed to be vendor-agnostic, offering a standardized set of YANG data models for network device configuration and operational state across various vendors. This approach facilitates consistent network automation and management by separating configuration from operational data.

"open YANG" is not a recognized or standardized programming model in the networking industry.

Native YANG models are proprietary and vendor-specific, which contradicts the requirement for a vendor-agnostic solution.

IETF YANG refers to foundational YANG modules standardized by the IETF, but OpenConfig specifically focuses on creating unified, vendor-agnostic models for comprehensive network device management beyond basic IETF models.
