Learn about a network control plane gRPC service that enables external controllers to inject and query entries into network device RIBs through this 28-minute NANOG presentation. Explore how the OpenConfig Abstract Forwarding Table (AFT) data model is leveraged for entry representation, eliminating the need for external entities to maintain full forwarding table ownership or comprehensive entry awareness. Discover the transactional nature of programming operations, including acknowledgment support for installed states in both device RIB and hardware FIB. Understand how the combination of gRPC and AFT data models enables vendor-neutral support for external entities managing network routing information.
