More concisely, setting the R bit outside of the deferred-selection period during startup is never useful. It means "don't wait for me, I'm still getting my own selection in order". It's a shortcut for "EoR on all AFIs/SAFIs". As soon as we're not in the deferred-selection period, we know when to send the AFI/SAFI EoR, and should do exactly that. That means R=0. And routers that don't implement a deferred-selection period would always send R=0. -David _______________________________________________ Quagga-dev mailing list [email protected] https://lists.quagga.net/mailman/listinfo/quagga-dev
