You can use VBST for spanning tree(command - stp mode vbst) and then have spanning tree engineering per vlan - like stp vlan 10 root primary

Procedure:

+ Perform the following operations on the device you want to use as the root bridge.
a. Run system-view
The system view is displayed.

b. Run stp vlan vlan-id [ to vlan-id ] [ vlan-id [ to vlan-id ] ] &<1-9> root primary
The device is configured as the root bridge.

By default, a switching device does not function as the root bridge. After you run this command, the priority value of the device is set to 0 and cannot be changed.
c. Run commit
The configuration is committed.

+Perform the following operations on the device you want to use as the secondary root bridge.
a. Run system-view
The system view is displayed.

b. Run stp vlan vlan-id [ to vlan-id ] [ vlan-id [ to vlan-id ] ] &<1-9> root secondary
The device is configured as the secondary root bridge.

By default, a switching device does not function as the secondary root bridge. After you run this command, the priority value of the device is set to 4096 and cannot be changed.

c. Run commit
The configuration is committed.
