Nicky,
Rapid-PVST uses the existing configuration for PVST+; however, Rapid-PVST
uses RSTP to provide faster convergence. Independent VLANs run their own
RSTP instance.
Dynamic entries are flushed immediately on a per-port basis upon receiving a
topology change.
UplinkFast and BackboneFast configurations are ignored in Rapid-PVST mode;
both features are included in RSTP.
HTH,
