A.可以實現(xiàn)更有效地利用帶寬，允許許多物理組使用相同的網(wǎng)絡(luò)基礎(chǔ)設(shè)施
B.廣播風(fēng)暴可以通過減少廣播域的數(shù)量，從而增加它們的尺寸來緩解
C.水平較高可以通過從其他網(wǎng)絡(luò)業(yè)務(wù)分離敏感的數(shù)據(jù)流量達(dá)到
D.基于端口的VLAN造成交換機(jī)端口的采用效率，這要歸功于802.1Q中繼可以實現(xiàn)

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.
