Rapid Spanning Tree Protocol (RSTP)

Overview

Rapid spanning tree protocol (RSTP) is a Layer 2 protocol—specified by IEEE 802.1w—that is essentially

the same as the spanning-tree protocol (STP) but provides faster convergence and interoperability with

switches configured with STP and multiple spanning tree protocol (MSTP).

FTOS supports three other variations of spanning tree (Table 27-1).

Configuring Rapid Spanning Tree

Configuring rapid spanning tree is a two-step process:

1. Configure interfaces for Layer 2.

2. Enable Rapid Spanning Tree Protocol.

Related Configuration Tasks

• Add and Remove Interfaces

• Modify Global Parameters

• Enable BPDU Filtering globally

• Modify Interface Parameters

• Configure an EdgePort

• Preventing Network Disruptions with BPDU Guard

• Influence RSTP Root Selection
