RFC9692 - RIFT: Routing in Fat Trees

This document defines a specialized, dynamic routing protocol for Clos, fat tree, and variants thereof. These topologies were initially used within crossbar interconnects and consequently router and switch backplanes, but their characteristics make them ideal for constructing IP fabrics as well. The protocol specified by this document is optimized towards the minimization of control plane state to support very large substrates as well as the minimization of configuration and operational complexity to allow for a simplified deployment of said topologies.

RFC9696 - Routing in Fat Trees (RIFT) Applicability and Operational Considerations

This document discusses the properties, applicability, and operational considerations of Routing in Fat Trees (RIFT) in different network scenarios with the intention of providing a rough guide on how RIFT can be deployed to simplify routing operations in Clos topologies and their variations.

RFC9719 - YANG Data Model for Routing in Fat Trees (RIFT)

This document defines a YANG data model for the configuration and management of the Routing in Fat Trees (RIFT) Protocol. The model is based on YANG 1.1, which is defined in RFC 7950 and conforms to the Network Management Datastore Architecture (NMDA) as described in RFC 8342.
