Ramesh, Merit has done studies on this in the past. Their data is on at http://www.merit.edu/ipma/reports/ That said, why are route flaps important? In the past, its been said that certain length prefixes were the cause of lots of routing instability on the Internet, and much effort was spent on developing elaborate dampening algorithms and policy efforts were spent on determining how to set the parameters on such a system. As it turns out, these aren't important ... prefixes flap pretty much independent of length. And while dampening will help prevent lots of up/down cyclic behavior and resulting churn, the whole issue, I think, got a lot more intellectual curiosity that it deserved, not to dissuade you ;) Other than it being something that one can count, I'm not sure why route flaps, in general, are interesting. -scott At 11:38 AM 9/17/97 -0400, Ramesh Kalathur wrote: >I have couple of questions on Route Flaps at NAP's. >1)How often do they happen?
