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 atates 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.
