config. RSTP

RSTP has the CONVERGENCE time around 1 second - it's time from topology change (primary path goes down) to a stable state (previously blocked redundant link goes into Forwarding mode). To speed up the time from the port become active to the time it starts forwarding traffic, use "spanning portfast" (or "spantree portfast" on IOS). There is no way to forward any port until the router actually load and run all software (time from power up).

Good luck,
