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-07.txt Pages : 155 Date : 2019-08-15 Abstract: This document outlines a specialized, dynamic routing protocol for Clos and fat-tree network topologies. The protocol (1) deals with fully automated construction of fat-tree topologies based on detection of links, (2) minimizes the amount of routing state held at each level, (3) automatically prunes and load balances topology flooding exchanges over a sufficient subset of links, (4) supports automatic disaggregation of prefixes on link and node failures to prevent black-holing and suboptimal routing, (5) allows traffic steering and re-routing policies, (6) allows loop-free non-ECMP forwarding, (7) automatically re-balances traffic towards the spines based on bandwidth available and finally (8) 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.
