[DeviceF] rrpp domain 1

# Configure Device F as the master node of subring 3 in RRPP domain 1, with GigabitEthernet 2/0/1 as
the primary port and GigabitEthernet 2/0/2 as the secondary port, and enable subring 3.
[DeviceF-rrpp-domain1] ring 3 node-mode master primary-port gigabitethernet 2/0/1

[DeviceF-rrpp-domain1] ring 3 enable
[DeviceF-rrpp-domain1] quit
# Enable RRPP.
[DeviceF] rrpp enable
7) RRPP ring group configurations on Device B and Device C after the configurations above
# Create RRPP ring group 1 on Device B, and add subrings 2 and 3 to the RRPP ring group.
[DeviceB] rrpp ring-group 1
[DeviceB-rrpp-ring-group1] domain 2 ring 2
[DeviceB-rrpp-ring-group1] domain 1 ring 3
# Create RRPP ring group 1 on Device C, and add subrings 2 and 3 to the RRPP ring group.
[DeviceC] rrpp ring-group 1
[DeviceC-rrpp-ring-group1] domain 2 ring 2
[DeviceC-rrpp-ring-group1] domain 1 ring 3
8) Verification
After the configuration, you can use the display command to view RRPP configuration and operational
information on each device.
Fast Detection Configuration Example
Network requirements
As shown in Figure 1-11 ,
z
Device A, Device B, Device C, and Device D constitute RRPP domain 1, VLAN 4092 is the primary
control VLAN of RRPP domain 1, and RRPP domain 1 protects all the VLANs.
z
Device A is the master node and supports RRPP fast detection; Device D is a transit node; Device
B and Device C do not support RRPP.
As neither Device B nor Device C supports RRPP, when the link between them fails, the link failure
cannot be detected by the master node timely. It is required to configure RRPP fast detection to
implement fast link switchover even when the link between Device B and Device C fails.
