Activating an RRPP domain
To activate an RRPP domain on the current device, enable the RRPP protocol and RRPP rings for the RRPP
domain on the current device.
Perform this operation on all nodes in the RRPP domain.
To prevent Hello packets of subrings from being looped on the primary ring, enable the primary ring on
its master node before enabling the subrings on their separate master nodes. On an edge node or
assistant-edge node, enable/disable the primary ring and subrings separately:
• Enable the primary ring of an RRPP domain before enabling the subrings of the RRPP domain.
• Disable the primary ring of an RRPP domain after disabling all subrings of the RRPP domain.
To activate an RRPP domain:

Command
Remarks
1. Enter system view.
system-view N/A
2. Enable RRPP.
rrpp enable Disabled by default.
3. Enter RRPP domain view.
rrpp domain domain-id N/A
4. Enable the specified RRPP
ring.
ring ring-id enable Disabled by default.
Configuring RRPP timers
Perform this configuration on the master node of an RRPP domain.
The Fail timer value must be equal to or greater than three times the Hello timer value.
To avoid temporary loops when the primary ring fails in a dual-homed-ring network, make sure that the
difference between the Fail timer value on the master node of the subring and that on the master node
of the primary ring is greater than twice the Hello timer value of the master node of the subring.
To configure RRPP timers:

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, adopt the RRPP ring group mechanism by assigning subrings with the same
edge node/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, and can only be configured on these two types of nodes.
Perform this configuration on both the edge node and the assistant-edge node in an RRPP domain.
