VLANs and sending Common-Flush-FDB packets to instruct all transit no des to update their own 
MAC entries and ARP/ND entries.  
Link down alarm mechanism 
The transit node, the edge node or the assistant-edge  node sends Link-Down packets to the master node 
immediately when they find any of its own ports belonging to an RRPP domain are down. Upon the 
receipt of a Link-Down packet, the master node releases the secondary port from blocking data VLANs 
and sending Common-Flush-FDB packet to instruct...

packets frequently. If more subrings are configured or if load balancing is configured for multiple 
domains, Device B and Device C will send or receive a mass of Edge-Hello packets.  
To reduce Edge-Hello traffic, you can assign Ring 2 and Ring 3 to an RRPP ring group configured on the 
edge node Device B and assign Ring 2 and Ring 3 to  an R RPP  ri ng  g roup c onfigu re d on D evice  C. Af ter  
such configurations, if all rings are activated, only Ring 2 on Device B sends Edge-Hello packets....

Intersecting rings 
As shown in Figure 16, two or more rings are in the network topology and two common nodes exist 
between rings. You only need to define an RRPP domain and configure one ring as the primary ring and 
the other rings as subrings.

Single-ring load balancing 
In a single-ring network, you can achieve load balancing by configuring multiple domains.  
As shown in Figure 18,
 Ring 1 is configured as the primary ring of both Domain 1 and Domain 2. 
Domain 1 and Domain 2 are configured with differ ent protected VLANs. In Domain 1, Device A is

RRPP.  
RRPP configuration task list 
You can create RRPP domains based on service planning, specify control VLANs and data VLANs for 
each RRPP domain, and then determine the ring roles  and node roles based on the traffic paths in each 
RRPP domain.  
Complete the following tasks to configure...

 63 
Task Remarks 
Configuring an RRPP ring group Optional  
Perform this task on the edge node and assistant-edge node 
in the RRPP domain. 
 
 
NOTE:  
•  RRPP does not have an auto election mechanism, so you must confi
gure each node in the ring network
properly for RRPP to monitor and protect the ring network.  
•   Before configuring RRPP, you must construct a ring-shaped Ethernet topology physically. 
 
Creating an RRPP domain 
When creating an RRPP domain, specify a domain ID , which uniquely...

3.  Configure the primary control VLAN for the RRPP 
domain.  control-vlan

Configuring protected VLANs 
Before configuring RRPP rings in an RRPP domain, co nfigure the same protected VLANs for all nodes in 
the RRPP domain first. All VLANs that the RRPP port s are assigned to should be protected by the RRPP 
domains.  
You can configure protected VLANs through referencing Multiple...

Specifying an edge node 
When configuring an edge node, you must first configure the primary ring before configuring the 
subrings.  
Perform this configuration on a device to be configured as an edge node.  
To specify an edge node: 
 
Step Command 
1.  Enter system view.  system-view 
2.  Enter RRPP domain view.

3.  Specify the current device as a transit node of the 
primary ring, and specify the primary port and 
the secondary port.  ring
