Figure 5 shows an example of an MSTP instance configured with the VLAN range option. All the
VLANs are included in the instance whether they exist or not. Figure 6 shows an example of an MSTP
instance configured on a ProCurve switch other than the Series 3500/5400/6200. Only VLANs 1, 5, and
7 are included in the instance.

The Configuration Digest value in Figure 6 is not the same as in Figure 5, indicating that these switches
do not operate in the same instance.
The Common Spanning Tree (CST) will still have the correct root associations.

Operating Notes
■ Configuring MSTP on the switch automatically configures the Internal Spanning Tree (IST)
instance and places all statically and dynamically configured VLANs on the switch into the
IST instance. The spanning-tree instance vlan command creates a new MST instance and
moves the VLANs you specify from the IST to the MSTI.
