Note:
MSTP-enabled switches are in the same region only when they have the same
format selector (a 802.1s-defined protocol selector, which is 0 by default and cannot
be configured), MST region name, VLAN-to-MSTI mapping table, and revision level.
The H3C series support only the MST region name, VLAN-to-MSTI mapping table,
and revision level. Switches with the settings of these parameters being the same
are assigned to the same MST region.
The configuration of MST region–related parameters, especially the VLAN-to-instance
mapping table, will cause MSTP to launch a new spanning tree calculation process,
which may result in network topology instability. To reduce the possibility of topology
instability caused by configuration, MSTP will not immediately launch a new spanning
tree calculation process when processing MST region–related configurations; instead,
such configurations will take effect only if you:
activate
region-configuration command, or
enable MSTP using the stp enable command.
