Rapid Spanning Tree Protocol (RSTP)
The Rapid Spanning Tree Protocol (RSTP) is a Layer 2 protocol specified by IEEE 802.1w that is essentially the same as
spanning-tree protocol (STP) but provides faster convergence and interoperability with switches configured with STP and
multiple spanning tree protocol (MSTP)..

Configuring Rapid Spanning Tree
Configuring RSTP is a two-step process.
1. Configure interfaces for Layer 2.
2. Enable the rapid spanning tree protocol.
