Integrating RIFT protocol into Junos OS

You can integrate Routing in Fat Tree (RIFT) into Junos OS to route packets in variants of CLOS-based and fat tree network topologies (also called the spine and leaf model). The RIFT protocol is capable of automatic construction of fat-tree topologies, providing you the benefit of having a close to zero necessary configuration. RIFT makes networks resilient, extensively traceable, and simpler to manage, thereby overcoming the deployment limitations of evolving IP fabrics.
