RPVST+ is Cisco's implementation of the IEEE 802.1w specification titled “Rapid Reconfiguration of Spanning Tree.” Beginning with IOS 15.2(4)E, RPVST+ replaces PVST+ as the default Spanning Tree mode. There are some significant differences between the two that we'll cover in a moment. But the configuration commands for RPVST+ and PVST+ are almost identical. PVST+ still exists only for backward compatibility with older equipment, but whenever possible, you should use RPVST+. If you encounter an older IOS version that has PVST+ enabled, you can enable RPVST+ by issuing the global configuration command spanning-tree mode rapid-pvst.
