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.
