Abstract:
   Route Flap Damping (RFD) was first proposed to reduce BGP churn in
   routers.  Unfortunately, RFD was found to severely penalize sites for
   being well-connected because topological richness amplifies the
   number of update messages exchanged.  Many operators have turned RFD
   off.  Based on experimental measurement, this document recommends
   adjusting a few RFD algorithmic constants and limits, to reduce the
   high risks with RFD, with the result being damping a non-trivial
   amount of long term churn without penalizing well-behaved prefixes'
   normal convergence process.
