Usage Guidelines

MSTP divides a switching network into multiple regions, each of which has multiple spanning trees that are independent of each other. Each region is called an MST region and each spanning tree is called a multiple spanning tree instance (MSTI).

Two switching devices belong to the same MST region only when they have the following same configurations:
  • MST region name
  • Mappings between MSTIs and VLANs
  • MST region revision level

If two switching devices have the same region name and VLAN mapping table, the revision-level command can be used to set different revision levels for the two devices so that the two devices belong to different MST regions.


# Set the MSTP revision level of the switching device to 5.
