Fast Detection Configuration Example - H3C S9500E Series Configuration Manual

[DeviceF-GigabitEthernet3/0/2] port trunk permit vlan 10
[DeviceF-GigabitEthernet3/0/2] quit
Create RRPP domain 1, configure VLAN 100 as the primary control VLAN, and configure the
VLAN mapped to MSTI 1 as the protected VLAN.
[DeviceF] rrpp domain 1
[DeviceF-rrpp-domain1] control-vlan 100
[DeviceF-rrpp-domain1] protected-vlan reference-instance 1
Configure Device F as the master node of subring 3 in RRPP domain 1, with GigabitEthernet
3/0/1 as the primary port and GigabitEthernet 3/0/2 as the secondary port, and enable
subring 3.
[DeviceF-rrpp-domain1] ring 3 node-mode master primary-port gigabitethernet
3/0/1 secondary-port gigabitethernet 3/0/2 level 1
[DeviceF-rrpp-domain1] ring 3 enable
[DeviceF-rrpp-domain1] quit
Enable RRPP.
[DeviceF] rrpp enable
RRPP ring group configurations on Device B and Device C after the configurations above
7.
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
Verification
8.
After the configuration, you can use the display command to view RRPP configuration result on
each device.

Fast detection configuration example

Network requirements
As shown in Figure 17:
•
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.
•
Device A is the master node and supports RRPP fast detection, providing a timer resolution of
10 milliseconds. 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. Configure RRPP fast detection to implement fast
link switchover even when the link between Device B and Device C fails.
