Abstract:
   In dense topologies (such as data center fabrics based on the Clos
   and butterfly topologies, though not limited to these), IGP flooding
   mechanisms designed for sparse topologies can "overflood," or carry
   too many copies of topology and reachability information to fabric
   devices.  This results in slower convergence times and higher
   resource utilization.  The modifications to the flooding mechanism in
   the Intermediate System to Intermediate System (IS-IS) link state
   protocol described in this document reduce resource utilization
   significantly, while increasing convergence performance in dense
   topologies.

   Note that a Clos fabric is used as the primary example of a dense
   flooding topology throughout this document.  However, the flooding
   optimizations described in this document apply to any topology.
