HA! Partially true. But either way, remember that BGP was designed for
stability and NOT to have the quantity of route calculations and updates
that IGP's happen to have. Whether your routers are capable of it or not,
is it really a good idea?

Only by providers who can't afford in this recession to upgrade their
router's to more powerful models that can handle the extra overhead.

Hi Scott,
Is it true that route dampening is consider obsolete?
It actually not recommended to be used anymore?
