Appendix D. Route Flap Damping

BGP Flap Damping Configuration

Recommended route flap-damping parameters for use by ISPs were composed into a document by the RIPE Routing Working Group and are available at www.ripe.net/docs/ripe-229.html. These values are used by many European and U.S. ISPs, and they are based on the operational experienced gained in the industry.

The current address list is documented at www.golden-networks.net —this site should be consulted prior to implementing RIPE-229 flap damping.
