Rapid Spanning Tree Protocol

Rapid Spanning Tree Protocol is supported on platforms: c e s

RSTP is supported on the E-Series ExaScale platform with FTOS 8.1.1.0 and later.

Protocol Overview

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 MSTP.

FTOS supports three other variations of Spanning Tree, as shown in Table 45-1.

Configuring Rapid Spanning Tree

Configuring Rapid Spanning Tree is a two-step process:

1. Configure interfaces for Layer 2. See page 48.

2. Enable Rapid Spanning Tree Protocol. See page 49.
