Route holdowns:

los pobres paquetos: that's just the beauty and purpose of routing 
protocols to propagate the info so that los pobres paquetos don't clog

To hold routes eternally down is not good: what if the customer 
disconnects that network? I don't want to be notified by all leaf 
networks when they will hickup or disconnect for good.
