Step 2 Run:
rrpp ring-group ring-group-id
An RRPP ring group is created.
The ring group can be only created on edge nodes or assistant edge nodes.
In an RRPP ring group, the nodes of all sub-rings must have the same type. That is, all of them
must be all edge nodes or assistant edge nodes.
Step 3 Run:
domain domain-id ring { ring-id1 [ to ring-id2 ] } &<1-10>
A sub-ring is added to the ring group.
The edge nodes of sub-rings in a ring group are the same device. Similarly, the assistant edge
nodes of sub-rings in a ring group are the same device.
A sub-ring can belong to only one ring group.
When creating a sub-ring or deleting a sub-ring, pay attention to the following:
l To add activated sub-rings in the ring group, configure relevant commands firstly on the
l To delete activated sub-rings from the ring group, configure relevant commands firstly on

3.4.11 (Optional) Configuring the Delay for Link Restoration

After the delay for link recovery is configured, the block port on the RRPP ring is not switched
immediately. Instead, the block port is switched when the delay timer expires, thus reducing the
flapping of the link status.
Context
The delay can take effect only when it is configured on a master node.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
rrpp linkup-delay-timer linkup-delay-timer-value
The delay timer for the switchover of block port is set.
The value of linkup-delay-timer-value must be smaller than or equal to the value of the Fail timer
minus 2 times HELLO timer in any domain.
