Configuring Rrpp Timers; Configuring An Rrpp Ring Group; Configuration Restrictions And Guidelines - HP 6125G Configuration Manual

Step
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.
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.
NOTE:
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.

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.

Configuration restrictions and guidelines

You can assign a subring to only one RRPP ring group. Make sure the RRPP ring group configured
•
on the edge node and the RRPP ring group configured on the assistant-edge node contain the same
subrings. Otherwise, the RRPP ring group cannot operate properly.
Make sure the subrings in an RRPP ring group share the same edge node and assistant-edge node
•
and that 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 the RRPP ring group on the assistant-edge
•
node have the same configurations and activation status.
• Make sure that 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 properly.
