1.2.2 MST Region Configuration
I. Configuration procedure
Follow these steps to configure an MST region:
To do ...
Enter system view
Enter MST region
view
Configure a name
for the MST region
Configure the VLAN
mapping table for
the MST region
Configure the MSTP
revision level for the
MST region
Activate the
configuration of the
MST region
manually
Display the
configuration of the
current MST region
Display the currently
valid configuration of
the MST region
Configuring MST region-related parameters (especially the VLAN mapping table)
results in spanning trees being regenerated. To reduce network topology jitter caused
by the configuration, MSTP does not regenerate spanning trees immediately after the
configuration; it does this only after you perform one of the following operations, and
then the configuration can really take effect:
Activating the new MST region-related settings by using the active
region-configuration command
Enabling MSTP by using the stp enable command
Use the command ...
system-view
stp region-configuration
region-name name
instance instance-id vlan
vlan-list
vlan-mapping modulo
modulo
revision-level level
active
region-configuration
check
region-configuration
display stp
region-configuration
