A.RSTP significantly reduces topology reconverging time after a link failure. B.RSTP expends the STP port roles by adding the alternate and backup roles. C.RSTP port states are blocking,discarding,learing,or forwarding. D.RSTP also uses the STP proprsal-agreement sequence. E.RSTP use the same timer-baseed process as STP on point-to-point links. F.RSTP provides a faster transition to the forwarding state on point-to-point links than STP does.
