Step Command Remarks
4. Specify the current device
as the assistant edge node
of the subring, and specify
an edge port.
ring ring-id node-mode assistant-edge
[ edge-port interface-type
interface-number ]
By default, the device is not a
node of the RRPP ring.
Activating an RRPP domain
Before you activate an RRPP domain on the current device, enable the RRPP protocol and RRPP rings for
the RRPP domain on the current device.
Follow these guidelines when you activate an RRPP domain:
•
Before you enable subrings on a device, you must enable the primary ring. Before you disable the
primary ring on the device, you must disable all subrings. Otherwise, the system displays error
prompts.
•
To prevent Hello packets of subrings from being looped on the primary ring, enable the primary
ring on its master node first. Then enable the subrings on their separate master nodes.
Perform this task on all nodes in the RRPP domain.
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.
