BGP Dampening: Some Thoughts
Should it be progressive?
Should it be aggregation biased? OK longer then /19 but liberal to shorter?
If the first flap was a withdraw, should the dampening restore the original route?
This will cause blackholing and possible routing loop for a multi-homed flapper.
A number of people are quite uncomfortable with restoring an up path as opposed to hold-down
