z
You can assign a subring to only one RRPP ring group. Make sure that 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.
z
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.
z
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.
z
Ensure that the RRPP ring group on the edge node and that on the assistant-edge node have the
same configurations and activation status.
z
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.
