Configuring Rrpp Timers; Configuring An Rrpp Ring Group - HPE FlexNetwork HSR6800 series Configuration Manual

•
Disable the primary ring of an RRPP domain after disabling all subrings of the RRPP domain.
To activate an RRPP domain:
Step
1. Enter system view.
2. Enable RRPP.
3. Enter RRPP domain view.
4. Enable the specified RRPP
ring.

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:
Step
1. Enter system view.
2. Enter RRPP domain view.
3. Configure the Hello timer
and Fail timer for the
RRPP domain.

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.
Follow these guidelines when you configure an RRPP ring group:
•
You can assign a subring to only one RRPP ring group. The RRPP ring group configured on the
edge node and that configured on the assistant-edge node must contain the same subrings.
Otherwise, the RRPP ring group cannot operate correctly.
•
Make sure the subrings in an RRPP ring group share the same edge node and assistant-edge
node, and the edge node and the assistant edge node have the same SRPTs.
•
Make sure a device plays the same role on the subrings in an RRPP ring group. The role can be
the edge node or the assistant-edge node.
•
Make sure the RRPP ring group on the edge node and that on 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 configured or modified differently, the RRPP ring group cannot operate correctly.
