Configuring MSTP

In order for MSTP to provide multiple forwarding paths, the following must happen:

• The configuration identifier must match on all bridges within the region.
• All bridges must be within the same region.
• All bridges must be connected to MSTP-aware bridges. (They can be connected using a shared media such as a repeater provided that a single Spanning Tree device does not reside on that LAN).
  

  Note

  A single Spanning Tree device between two MSTP bridges will terminate the ability to have multiple forwarding paths.
