[edit protocols]
user@switch4# mstp configuration-name region1
user@switch4# mstp bridge-priority 16k
user@switch4# mstp interface ge-0/0/23 cost 1000
user@switch4# mstp interface ge-0/0/23 mode point-to-point
user@switch4# mstp interface ge-0/0/19 cost 1000
user@switch4# mstp interface ge-0/0/19 mode point-to-point
user@switch4# mstp msti 1 bridge-priority 16k
user@switch4# mstp msti 1 vlan [10 20]
user@switch4# mstp msti 2 bridge-priority 32k
user@switch4# mstp msti 2 vlan [30 40]
