Chapter 23: Multiple Spanning Tree Protocol
252
Section V: Spanning Tree Protocols
Figure 27 illustrates the same two AT-9400 Switches and the same two
virtual LANs. But in this example, the two switches are running MSTP and
the two VLANs have been assigned different spanning tree instances.
Now that they reside in different MSTIs, both links remain active, enabling
the VLANs to forward traffic over their respective direct link.
