Configuring a Protected VLAN

Procedure

1. Run system-view

   The system view is displayed.

2. Run rrpp domain domain-id

   The RRPP domain view is displayed.

3. Run protected-vlan reference-instance { { instance-id1 [ to instance-id2 ] } &<1-10> | all }

   The list of protected VLANs in the RRPP domain is configured.

   All the VLANs whose packets need to pass through an RRPP interface, including the control VLANs and data VLANs, must be configured as protected VLANs.

   

   When you configure the list of protected VLANs, note the following points:

   • Protected VLANs must be configured before you configure an RRPP ring.

   • You can delete or change existing protected VLANs before configuring an RRPP ring. The protected VLANs cannot be changed after the RRPP ring is configured.

   • In the same physical topology, the control VLAN in a domain cannot be configured as a protected VLAN in another domain.

   • The control VLAN must be included in the protected VLANs; otherwise, the RRPP ring cannot be configured.

   • The control VLAN can be mapped to other instances before the RRPP ring is created. After the RRPP ring is created, the mapping cannot be changed unless you delete the RRPP ring.

   • When the mapping between an instance and VLANs changes, the protected VLANs in the RRPP domain also change.

   • All the VLANs allowed by an RRPP interface must be configured as protected VLANs.
