Configuration of MSTP on Juniper SRX connected to a Cisco switch

Can somebody convert the below MSTP configuration on the Cisco to SRX or confirm it is right:

Cisco Switch:

spanning-tree mst configuration

name region1

revision 1

instance 1 vlan 1-4094

exit

spanning-tree mode mst

SRX:

edit protocols mstp

set Configuration-name region1

set revision-level 1

set msti 1 vlan [1-4094]

set protocols mstp interface all

Shall i enable mstp on the all the irb or it is not supported, maybe the irb comes under the all or maybe a i can't enable it besides the on physical interfaces (correct if i'm wrong)
