Note: Rapid PVST+ is the Cisco implementation of RSTP on a per-VLAN basis. With Rapid PVST+ an independent instance of RSTP runs for each VLAN
Users that are familiar with the original STP standard can easily configure RSTP. The same spanning tree algorithm is used for both STP and RSTP to determine port roles and topology
RSTP increases the speed of the recalculation of the spanning tree when the Layer 2 network topology changes
If a port is configured to be an alternate port it can immediately change to a forwarding state without waiting for the network to converge
