just what i have gathered on my own (aka a guess)...
The ciscos have various scan times. The purpose is to minimize churn and/or
route-flapping. So if a route flaps in one routing-domain/protocol it will be
limited to flapping at the rate of the scan time in the routing-domain/protocol
it is being redistributed into. Scan times are about 1 minute to 15 seconds and
are basically undocumented.
an LSA has an age time and will age out (1 or 3 hours??? check the RFC).
