11.1.4 Multiple RSTP
MRSTP (Multiple RSTP) is ZyXEL’s proprietary feature that is compatible with RSTP and STP. With MRSTP, you can have more than one spanning tree on your switch and assign port(s) to each tree. Each spanning tree operates independently with its own bridge information.
In the following example, there are two RSTP instances (MRSTP 1 and MRSTP2) on switch A.
To set up MRSTP, activate MRSTP on the switch and specify which port(s) belong to which spanning tree.
Note: Each port can belong to one STP tree only.

11.2 Spanning Tree Protocol Main Screen
The switch allows you to configure a single RSTP configuration or you can configure multiple configurations. Click Advanced Application, Spanning Tree Protocol in the navigation panel to choose whether you want to configure multiple or a single Spanning Tree Protocol configuration.
Note: This screen is only available if neither RSTP or MRSTP is active. Once you select RSTP or MRSTP this screen displays the status of your configuration.
