Configuring An Rrpp Ring Group - H3C S9500E Series Configuration Manual

The value of the Fast-Fail timer must be equal to or greater than three times the Fast-Hello timer.
•
In a dual-homed-ring network, to avoid temporary loops when the primary ring fails, ensure that the Fast-
•
Fail timer value is equal to or greater than six times the timer resolution, and the difference between the
Fast-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 Fast-Hello timer value of the master node of the subring.

Configuring an RRPP ring group

To reduce Edge-Hello traffic, you can adopt the RRPP ring group mechanism, that is, assign
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.
To configure an RRPP ring group:
To do...
1. Enter system view
2. Create an RRPP ring group and enter
RRPP ring group view
3. Assign the specified subrings to the
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 normally.
Ensure that 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.
Ensure that a switch plays the same role on the subrings in an RRPP ring group. The role can be the
•
edge node or the assistant-edge node.
Ensure that the RRPP ring group on the edge node and that on the assistant-edge node have the same
•
configurations and activation status.
Ensure 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 normally.
