8.4.4.5 ERP Ring Priority
The Super Loop occurs because of a shared link’s failure between two ERP rings. A do-
main with higher priority (one of the RM nodes) is the only responsible for monitoring the
ports of a shared link. The control packets of a domain with lower ring priority can be
transmitted to another domain with higher priority to prevent the super loop.
It means that the higher ring priority domain guarantees the detour path against a shared
link of lower ring priority domain.
To specify ERP ring priority, use the following command.
