Configuring Rapid Spanning Tree

The Classic Spanning Tree prevents L2 forwarding loops in a general network topology. However, convergence can take up to 30-60 seconds. The
convergence time is considered too long for many applications. When network topology allows, faster convergence may be possible. The Rapid Spanning Tree
Protocol (RSTP) detects and uses network topologies that provide faster convergence of the spanning tree without creating forwarding loops.
