RIFT (Routing In Fat-Trees) is being designed as next-gen routing protocol optimized for leaf/spine architectures, taking advantage of somewhat deterministic network topologies (CLOS) common to hyperscale datacenters. Large datacenters have known challenges with IGP, pushing the engineers towards BGP, which requires enough tweaks and cumbersome configurations, vouching the need for alternate solutions. RIFT also adds autonomous routing, empowering the routers to identify their relative roles and start routing traffic autonomously. RIFT has been gaining attention at IETF. There is a formal RIFT working group formed in the past IETF meeting (London). Juniper, Comcast and Cisco have been contributing heavily towards the specifications.
