please allow me to add the pointer to the also wished "noise
suppression" in OSPF, where a delay between appearance or disappearance
of a route and it's propagation to the neighbours would also improve the
stability of the landscape and lower the "noise" caused by flapping
routes. (Cisco boxes behave this way, from our observations.)
