Usage Scenario

ERPSv1 and ERPSv2 are currently available. ERPSv2 supports multi-ring topologies in addition to single ring topologies.
To deploy ERPS on a multi-ring network, you must configure some rings as sub-rings.
Major rings are closed, and sub-rings are open.

Prerequisites

The version v2 command has been run to specify ERPSv2.
The ERPS ring does not have any port. If the ERPS ring has a port, run the undo erps ring ring-id or undo port interface-type interface-number command to remove the port from the ERPS ring.

# Configure ERPS ring 5 as a sub-ring.
