Hi, just a heads up in regard to ripe-580. It states that "The default values used in current implementations of RFD apply a penalty of 1000 each time a route flaps". At least for Juniper that is not the case. Or to quote them directly: A figure-of-merit value of zero is assigned to each new route. The value is increased each time the route is withdrawn or readvertised, or when one of its path attributes changes. With each incident of instability, the value increases as follows: Route is withdrawn: 1000 Route is readvertised: 1000 Route's path attributes change: 500 Note: Other vendors' implementations for figure-of-merit increase the value only when a route is withdrawn. The Junos OS implementation for figure-of-merit increases the value for both route withdrawal and route readvertisement. To accommodate other implementations for figure-of-merit, multiply the reuse and suppress threshold values by 2. So yeah, if you want to use ripe-580 on Junos gear you should probably multiply the suppress/cutoff value by 2.
