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.
