Permanent Spanning-tree Root Switch Question

Hi,

I am considering a spanning-tree task (dont have the answers tho).

*It requires that, of the four switches in the network, SW1 be set as the
root for VLANs 20, 30, 40.*
**
*SW1 should be set such that it would remain the root if even other switches
are added to the network in future.*

Would setting a command like *'spanning-tree vlan 20,30,40 priority 0'* be a
good solution?

I'm afraid the *'spanning-tree vlan 20,30,40 root primary'* command may not
be able to cater for the 'future switches' caveat.

Let me have your expert opinions, please.

Regards,

Felix
