We hope you enjoyed reading part 1 of these series of articles focused on IP fabrics. In part 1 the authors provided background and foundational information to help understand the state of routing in IP fabrics. In this article, the authors provide a new perspective on how to address the challenges that this technology faces and introduce a new routing protocol, Routing in Fat Trees (RIFT), currently being standardized in IETF (Internet Engineering Task Force). RIFT is a dynamic routing protocol that is tailored for use in Clos, Fat-Tree, and other anisotropic topologies and attempts to provide a highly robust, zero touch provisioning to what it is a rather complex system. As they write in the article: “One of the gnarliest dragons operators have had to battle is what it takes to deploy IP fabrics, and very few make it out unscathed.” Let’s see how this new protocol allows the operators to slay the dragons of IP Fabric deployment and management.
