   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.
