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

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.

3.4.12 (Optional) Setting the Hello Timer and Fail Timer of an RRPP
Domain
Two timers, that is, the Hello timer and the Fail timer are used when master nodes are sending
and receiving RRPP protocol packets. The Hello timer is used when primary ports are sending
Hello packets. The Fail timer is used when secondary ports are receiving the Hello packets sent
by the local node.
Context
Do as follows on the master node in the RRPP domain:
