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.
