• Device A, Device B, Device C, and Device D form RRPP domain 1. Specify the primary control VLAN
of RRPP domain 1 as VLAN 4092, and specify that RRPP domain 1 protects VLANs 1 through 30.
• Device A, Device B, Device C and Device D form primary ring 1.
Specify Device A as the master node of primary ring 1, GigabitEthernet 3/0/1 as the primary port and
GigabitEthernet 3/0/2 as the secondary port.
Specify Device B, Device C and Device D as the transit nodes of primary ring 1, their GigabitEthernet
3/0/1 as the primary port and GigabitEthernet 3/0/2 as the secondary port.

Configuration procedure
1. Configure Device A:
# Create VLANs 1 through 30, map these VLANs to MSTI 1, and activate the MST region
configuration.
<DeviceA> system-view
[DeviceA] vlan 1 to 30
[DeviceA] stp region-configuration
[DeviceA-mst-region] instance 1 vlan 1 to 30
[DeviceA-mst-region] active region-configuration
[DeviceA-mst-region] quit
# Set the physical state change suppression interval to 0 seconds on GigabitEthernet 3/0/1 and
GigabitEthernet 3/0/2, disable the spanning tree feature, configure the two ports as trunk ports,
and assign them to VLANs 1 through 30.
