You can configure ring groups only on edge nodes or assistant-edge nodes.  

z 

A subring can be assigned to only one ring group.  

z 

A device must be of the same type, an edge node or an assistant-edge node, in the subrings in a 

ring group.  

z 

To assign an activated ring to a ring group, first assign the ring to the assistant-edge node ring 

group and then to the edge node ring group.  

z 

To remove an activated ring from a ring group, first remove the ring from the edge node ring group 

and then from the assistant-edge node ring group.  

z 

The subrings in a ring group must have the same link in the primary ring. Otherwise, the ring group 

cannot function properly.  

z 

An edge node ring group and its corresponding assistant-edge node ring group must be the same 

in configurations and activation status.

reference-instance instance-id-list: Specifies the MSTIs to be referenced. The range of the 

instance-id-list argument is as specified in the command configuring MSTIs.  

Use the protected-vlan command to configure the protected VLANs for the RRPP domain. The 

protected VLANs are specified by the MSTIs. You can use the display stp region-configuration 

command to check the VLANs corresponding to the specified MSTIs.  

Use the undo protected-vlan command to remove the protected VLANs of the RRPP domain. If no 

MSTI is specified, all protected VLANs of the RRPP domain are removed.  

By default, no protected VLAN is specified for an RRPP domain.
