To activate an RRPP domain:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enable RRPP.
rrpp enable
By default, RRPP is disabled.
3. Enter RRPP domain view.
rrpp domain
domain-id
N/A
4. Enable the specified RRPP
ring.
ring
ring-id
enable
By default, an RRPP ring is
disabled.
Configuring RRPP timers
The Fail timer must be greater than or equal to three times the Hello timer.
In a dual-homed-ring network, make sure the difference between the Fail timer values on the master
node of the subring and the master node of the primary ring is greater than twice the Hello timer
value on the master node of the subring. Otherwise, temporary loops might occur when the primary
ring fails.
Perform this task on the master node of an RRPP domain.
To configure RRPP timers:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter RRPP domain view.
rrpp domain
domain-id
N/A
3. Configure the Hello timer
and Fail timer for the
RRPP domain.
timer hello-timer
hello-value
fail-timer
fail-value
By default, the Hello timer value is 1 second
and the Fail timer value is 3 seconds.
Configuring an RRPP ring group
To reduce Edge-Hello traffic, assign subrings with the same edge node and 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. It can only be configured on these two types of nodes.
Follow these guidelines when you configure an RRPP ring group:
• You can assign a subring to only one RRPP ring group. The RRPP ring groups configured on
the edge node and the assistant edge node must contain the same subrings. Otherwise, the
RRPP ring group cannot operate correctly.
• The subrings in an RRPP ring group must share the same edge node and assistant edge node.
The edge node and the assistant edge node must have the same SRPTs.
• Make sure a device is either the edge node or the assistant edge node on the subrings in an
RRPP ring group.
• Make sure the RRPP ring groups on the edge node and the assistant edge node have the same
configurations and activation status.
• Make sure all subrings in an RRPP ring group have the same SRPTs. If the SRPTs of these
subrings are different, the RRPP ring group cannot operate correctly.
Perform this task on both the edge node and the assistant edge node in an RRPP domain.
