Remarks
Configure the Hello timer and Fail
timer for the RRPP domain
timer hello-timer hello-value fail-
timer fail-value
Required
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.
Follow these steps to configure an RRPP ring group:

Required
NOTE:
 You can assign a subring to only one RRPP ring group. 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.
 Ensure that 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.
 Ensure that 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.
 Ensure that 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.
 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 properly.
