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).
Protocol Overview
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).
The Dell Networking OS supports three other variations of spanning tree, as shown in the following table.

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