To configure interfaces and MSTP on Switch 1:
NOTE: Starting with Junos OS Release 15.1 for EX Series and QFX Series
switches with support for the Enhanced Layer 2 Software (ELS) configuration
style, you can configure spanning tree parameters globally on all spanning
tree interfaces. See
Configure the VLANs
1.
[edit vlans]
user@switch1# set voice-vlan description "Voice VLAN"
user@switch1# set voice-vlan vlan-id 10
user@switch1# set employee-vlan description "Employee VLAN"
user@switch1# set employee-vlan vlan-id 20
user@switch1# set guest-vlan description "Guest VLAN"
user@switch1# set guest-vlan vlan-id 30
user@switch1# set camera-vlan description "Camera VLAN"
user@switch1# set guest-vlan vlan-id 40
Configure the VLANs on the interfaces, including support for the Ethernet Switching

protocol:
[edit interfaces]
user@switch1# set ge-0/0/13 unit 0 family ethernet-switching vlan members [10 20 30
40]
user@switch1# set ge-0/0/9 unit 0 family ethernet-switching vlan members [10 20 30
40]
user@switch1# set ge-0/0/11 unit 0 family ethernet-switching vlan members [10 20 30
40]
Configure the port mode for the interfaces:

[edit interfaces]
user@switch1# set ge-0/0/13 unit 0 family ethernet-switching interface-mode trunk
user@switch1# set ge-0/0/9 unit 0 family ethernet-switching interface-mode trunk
user@switch1# set ge-0/0/11 unit 0 family ethernet-switching interface-mode trunk
Configure MSTP on the switch, including the two MSTIs:

[edit protocols]
user@switch1# mstp configuration-name region1
user@switch1# mstp bridge-priority 16k
user@switch1# mstp interface ge-0/0/13 cost 1000
