Tony,
you might want to be a bit more specific about the values you are using, i.e. how long certain prefixes will be ignored. This will make troubleshooting easier and reduce calls into your NOC.
This brings up an interesting question too: Can we still troubleshoot the connectivity problems arising if transit ISPs use all different values for this or even the proposed exponential version?

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 ? --Tony
