> 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.
