Hi,
Thanks for sharing your opinion on the disabling of damping as a BCP.
Yes, this is something that we've taken into consideration.
However, route flap damping is still in use in a number of networks
out there.
Thus, we would like to obtain feedback on how the damping of a flap by
a transit provider may affect our connectivity.
Are you multihomed to this transit? To other upstreams? Depending on
the RFD implementation, withdrawal triggered suppression will indeed
affect your connectivity. For analysis of arguments against RFD,
specifically how it applies to your case, read the sigcomm
presentation, <http://conferences.sigcomm.org/sigcomm/2002/papers/
routedampening.html>. White paper is available via the ACM portal,
