Do consider ;
This Routing Working Group document proposes that with the current implementations of BGP flap damping, the application of flap damping in ISP networks is NOT recommended. The recommendations given in ripe-229 and previous documents  are considered obsolete henceforth.
If flap damping is implemented, the ISP operating that network will cause side-effects to their customers and the Internet users of their customers' content and services as described in the previous sections. These side-effects would quite likely be worse than the impact caused by simply not running flap damping at all.
With current vendor implementations, BGP flap damping is harmful to the reachability of prefixes across the Internet. We would like to encourage more work to correct some of the issues highlighted by the work of Mao et al , to allow the viewing of prefix flap statistics without applying flap damping, and permit more flexible per eBGP neighbour damping configuration features for network operators.
