sometimes , we want to add new vlan to the stp instance.
but after input the new vlan-id to the instance .check,The instance only have the old vlan-id.

before:
[Huawei]stp region-configuration 
[Huawei-mst-region]instance 1 vlan 1
[Huawei-mst-region]active region-configuration 
[Huawei-mst-region]display this
#
stp region-configuration
 instance 1 vlan 1
 active region-configuration
#
return

test:
[Huawei-mst-region]instance 1 vlan 2
[Huawei-mst-region]display this
#
stp region-configuration
 instance 1 vlan 1
 active region-configuration
#
return

so each time we modify region-configuration, active region-configuration needs to be used.

Hello,
configuring MST region parameters, especially VLAN mapping tables for MST regions, is likely to cause network topology flapping. To reduce network flapping, make sure that newly configured MST region parameters take effect only after the active region-configuration command is run.
Seems this command needs to be enabled each time.
