Enabling Rapid Spanning Tree Protocol Globally
Enable RSTP globally on all participating bridges; it is not enabled by default.
When you enable RSTP, all physical and port-channel interfaces that are enabled and in Layer 2 mode are
automatically part of the RST topology.
• Only one path from any bridge to any other bridge is enabled.
• Bridges block a redundant path by disabling one of the link ports.
To enable RSTP globally for all Layer 2 interfaces, use the following commands.
