a little contest here. what is the largest or most complex (measured in the number of parms) route flap damping confuration in actual use? send yours to me privately, and i will announce the winner in a few days (with their consent), and maybe show the config (with their consent). thanks for playing. and please, let's not get into the [de]merits of using rfd, how you should configure it, etc. this is research, and it is really about rfd parameter config complexity. randy
