Not just opinion, fact. If you see everything, ORR does nothing but adds cost. You only need AddPath and ORR, when everything is too expensive, but you still need good choices. But even if you have resources to see all, you may not actually want to have a lot of useless signalling and overhead, as it'll add convergence time and risk of encouraging rare bugs to surface. In the case where I deployed it, having all was not realistic possibly, in that, having all would mean network upgrade cycle is determined when enough peers are added, causing RIB scale to demand triggering full upgrade cycle, despite not selling the ports already paid. You shouldn't need to upgrade your boxes, because your RIB/FIB doesn't scale, you should only need to upgrade your boxes, if you don't have holes to stick paying fiber into. -- ++ytti _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
