Implementation In<strong>for</strong>mation<br />

• The <strong>FTOS</strong> MSTP implementation is based on IEEE 802.1Q-2003, and interoperates only with bridges<br />

that also use this standard implementation.<br />

• MSTP is compatible with STP and RSTP.<br />

• <strong>FTOS</strong> supports only one MSTP region.<br />

• When you enable MSTP, all ports in Layer 2 mode participate in MSTP.<br />

Configure Multiple Spanning Tree Protocol<br />

Configuring Multiple Spanning Tree is a two-step process:<br />

1. Configure interfaces <strong>for</strong> Layer 2. See page 387.<br />

2. Enable Multiple Spanning Tree Protocol. See page 421.<br />
