[DeviceA-rrpp-domain1] ring 1 enable
[DeviceA-rrpp-domain1] quit
# Enable RRPP.
[DeviceA] rrpp enable
2) Configuration on Device B
# Set the physical state change suppression interval on GigabitEthernet2/0/1 and
GigabitEthernet2/0/2 to 0 seconds, disable STP, configure the two ports as trunk ports, and
assign them to all VLANs.
<DeviceB> system-view
[DeviceB] interface gigabitethernet 2/0/1
[DeviceB-GigabitEthernet2/0/1] link-delay 0
[DeviceB-GigabitEthernet2/0/1] undo stp enable
[DeviceB-GigabitEthernet2/0/1] port link-type trunk
[DeviceB-GigabitEthernet2/0/1] port trunk permit vlan all
[DeviceB-GigabitEthernet2/0/1] quit
[DeviceB] interface gigabitethernet 2/0/2
[DeviceB-GigabitEthernet2/0/2] link-delay 0
[DeviceB-GigabitEthernet2/0/2] undo stp enable
[DeviceB-GigabitEthernet2/0/2] port link-type trunk
[DeviceB-GigabitEthernet2/0/2] port trunk permit vlan all
[DeviceB-GigabitEthernet2/0/2] quit
# Create RRPP domain 1, configure VLAN 4092 as the primary control VLAN of RRPP domain 1,
and configure the VLANs mapped to MSTIs 0 through 31 as the protected VLANs of RRPP
domain 1.
[DeviceB] rrpp domain 1
[DeviceB-rrpp-domain1] control-vlan 4092
[DeviceB-rrpp-domain1] protected-vlan reference-instance 0 to 31
# Configure Device B as the transit node of primary ring 1, with GigabitEthernet 2/0/1 as the
primary port and GigabitEthernet 2/0/2 as the secondary port, and enable ring 1.
[DeviceB-rrpp-domain1] ring 1 node-mode transit primary-port gigabitethernet 2/0/1
secondary-port gigabitethernet 2/0/2 level 0
[DeviceB-rrpp-domain1] ring 1 enable
[DeviceB-rrpp-domain1] quit
# Enable RRPP.
[DeviceB] rrpp enable
3) Configuration on Device C
The configuration on Device C is similar to that on Device B and thus omitted here.
4) Configuration on Device D
The configuration on Device D is similar to that on Device B and thus omitted here.
5) Verification
After the above configuration, you can use the display command to view RRPP configuration
and operational information on each device.
