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.
