The IESG has received a request from the Inter-Domain Routing WG (idr) to consider the following document: - 'Making Route Flap Damping Usable' <draft-ietf-idr-rfd-usable-03.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-09-23. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-idr-rfd-usable/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-idr-rfd-usable/ballot/ No IPR declarations have been submitted directly on this I-D.
