My reading of the draft (which can be wrong) is that the above sentence allows each implementation to chose any default value and hence override RFC 4271 recommendation to have a lower value for iBGP MRAI than for eBGP MRAI. As an alternative, what about removing the second sentence? ("The appropriate choice of default values is left to the discretion of implementors.") IMO the first sentence is clear enough ( "The suggested default values for the MinRouteAdvertisementIntervalTimer given in [RFC4271] are deprecated") > Going beyond that likely only leads to an argument. ;) My point was that the second sentence already goes a bit beyond. But really no big deal. It's up to you.
