Rapid Spanning Tree Protocol (RSTP)
The Rapid Spanning Tree Protocol (RSTP) is a Layer 2 protocol — specied by IEEE 802.1w — that is essentially the same as spanning-
tree protocol (STP) but provides faster convergence and interoperability with switches congured with STP and multiple spanning tree
protocol (MSTP).
Protocol Overview
RSTP is a Layer 2 protocol — specied by IEEE 802.1w — that is essentially the same as spanning-tree protocol (STP) but provides faster
convergence and interoperability with switches congured with STP and multiple spanning tree protocol (MSTP).
The Dell EMC Networking OS supports three other variations of spanning tree, as shown in the following table.

Conguring Rapid Spanning Tree
Conguring RSTP is a two-step process.
1 Congure interfaces for Layer 2.
2 Enable the rapid spanning tree protocol.
