Dear RIPE Routing WG There's an internet draft that is trying to gather data on route flap damping/dampening deployment status. http://tools.ietf.org/html/draft-shishio-grow-isp-rfd-implement-survey-01 This work is intended to gather background data on making the feature less harmful and more usable. We would very much appreciate if you would take the time to answer the following survey. https://www.surveymonkey.com/s/rfd-survey Thanks in advance for your time! other references: http://tools.ietf.org/agenda/80/slides/grow-5.pptx http://tools.ietf.org/agenda/80/slides/idr-5.pdf Regards, -Shishio -- Shishio Tsuchiya <shtsuchi(a)cisco.com>
