   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

      deals with no configuration, fully automated construction of fat-
      tree topologies based on detection of links,

      minimizes the amount of routing state held at each level,

      automatically prunes and load balances topology flooding exchanges
      over a sufficient subset of links,

      supports automatic disaggregation of prefixes on link and node
      failures to prevent black-holing and suboptimal routing,

      allows traffic steering and re-routing policies,

      allows loop-free non-ECMP forwarding,

      automatically re-balances traffic towards the spines based on
      bandwidth available and finally

      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.
