RSTP optimizes this by using P2P lilnks and taking up to only 2 seconds to converge. RPVST+ Is basically when you mix the two above. You have an instance of rapid STP running per VLAN. Also, some use MST which is another variance of STP which can group several VLANs to be part of...

第一条是把交换机的生成树模式由默认的STP改成RSTP(快速生成树),第二条是将交换机的接口启动portfast,这样 思科交换机配置中spanning-tree mode rapid-pvst什么意思 把交换机的生成树模式由默认的STP改成RSTP(快速生成树)。 在思科设备中,rapid-pvst是指把交换机的生成树模式由默认的STP改成RSTP(快速生成...点...
RPVST+ Is basically when you mix the two above. You have an instance of rapid STP running per VLAN. Also, some use MST which is another variance of STP which can group several VLANs to be part of a single MST region (and behave like RSTP inside that region). MST is useful because...
Unlikely i think although PVST+ and 802.1d should become largely unused due to Rapid-PVST+ and RSTP. If your switches support Rapid-PVST+ then there really is no reason to run PVST+ anymore. Note also that Rapid-PVST+ is backwards compatible with PVST+ so you can run both in your netwo...
