Usage Guidelines

protected-instance <msti> is the MSTP instance that are protected by the ring instance, so MSTP instance and VLAN mapping needs to be configured before configure ERPS by using command: set protocols spanning-tree mstp msti <msti> vlan <vlan-id>.

Make sure that the control VLAN and data VLANs of the ERPS ring have all been mapped to the MSTP instance.

The traffic of MSTP instance 0 is blocked by ERPS ring.

Multiple protected-instance (protected MSTP instance) can be added to one ERPS instance.
