A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Routing In Fat Trees WG of the IETF. Title : RIFT: Routing in Fat Trees Authors : Tony Przygienda Alankar Sharma Pascal Thubert Bruno Rijsman Dmitry Afanasiev Filename : draft-ietf-rift-rift-12.txt Pages : 163 Date : 2020-05-26 Abstract: This document defines a specialized, dynamic routing protocol for Clos and fat-tree network topologies optimized towards minimization of configuration and operational complexity. The protocol o deals with no configuration, fully automated construction of fat- tree topologies based on detection of links, o minimizes the amount of routing state held at each level, o automatically prunes and load balances topology flooding exchanges over a sufficient subset of links, o supports automatic disaggregation of prefixes on link and node failures to prevent black-holing and suboptimal routing, o allows traffic steering and re-routing policies, o allows loop-free non-ECMP forwarding, o automatically re-balances traffic towards the spines based on bandwidth available and finally o provides mechanisms to synchronize a limited key-value data-store that can be used after protocol convergence to e.g. bootstrap higher levels of functionality on nodes.
