Perform this configuration on the master node in the RRPP domain to be configured.  

Follow these steps to configure RRPP fast detection timers: 

Enter system view 

— 

Enter RRPP domain view 

rrpp domain domain-id 

— 

Configure the Fast-Fail timer 

timer fast-fail-timer 
fast-fail-value 

Optional 

By default, the Fast-Fail timer is 
600ms.  

Configure the Fast-Hello timer 

timer fast-hello-timer 
fast-hello-value 

Optional 

By default, the Fast-Hello timer 
is 200ms.  

 

z 

The value of the Fast-Fail timer must be equal to or greater than three times the Fast-Hello timer.  

z 

In a dual-homed-ring network, to avoid temporary loops when the primary ring fails, ensure that the 

Fast-Fail timer value is equal to or greater than 600ms, and the difference between the Fast-Fail 

timer value on the master node of the subring and that on the master node of the primary ring is 

greater than twice the Fast-Hello timer value of the master node of the subring.  

 

To reduce Edge-Hello traffic, you can adopt the RRPP ring group mechanism, that is, assign subrings 

with the same edge node/assistant-edge node to an RRPP ring group. An RRPP ring group must be 

configured on both the edge node and the assistant-edge node, and can only be configured on these 

two types of nodes.  

Perform this configuration on both the edge node and the assistant-edge node in an RRPP domain.  

Follow these steps to configure an RRPP ring group: 

Enter system view 

— 

Create an RRPP ring group 
and enter RRPP ring group 
view 

rrpp ring-group ring-group-id 

Required 

Assign the specified subrings to 
the RRPP ring group
