The IESG has approved the following document: - 'Making Route Flap Damping Usable' (draft-ietf-idr-rfd-usable-04.txt) as Proposed Standard This document is the product of the Inter-Domain Routing Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-idr-rfd-usable/ Technical Summary BGP Route Flap damping seeks to reduce the BGP churn in routers. First described in operators forms (RIPE, [ripe178]) and RFC2430 it was harsh penalizing sites for being well-connected because topology riches amplified the number of updates. Therefore, many operators turned it off [ripe378]. However, now because new measurements f[plesser2011] indicates a different suppression hold (6000) BGP update rate can be reduced by 19%. Ripe, a European Operator forum, has endorse these new settings [ripe580]. The Japanese operators have reported their use of the new RFD and their desires for implementation [shishio-grow-isp-rfd-implement-survey]. Working Group Summary WG Group had consensus over the last call. During the last call, a suggestion for addition features was made. The chairs/WG suggested this would be a follow-on draft rather than an addition to the current draft. Document Quality Existing implementation of RFD exist in Juniper and Cisco. Protocol deployments [shishio-grow-isp-rfd-implement-survey] found bugs which have been fixed. The Japanese operator and RIPE operator community have reviewed these documents, and the Japanese operator community given the response in [shishio-grow-isp-rfd-implement-survey]. Personnel Shepherd: Susan Hares (WG chair), AD: Stewart Bryant RFC Editor Note The title of Table 1 OLD Default RFD Paramaters of Juniper and Cisco NEW The default RFD parameters for Cisco and Juniper provided for the information of the reader.
