Well currently /24 and greater for 'around' 3 hours
/22 /23 for about an hour
everything else defaults to about 25 minutes.

But it depends on the flap frequency. Continual flapping will drive the
times up untill they hit an upper limit of 255 for /24+ and 90 minutes
for /22 and /23

Is there a possibility that we could have a discussion on this at the
next RIPE and possibly agree pan-european values to use ?
