Creating an Instance

Creating an Instance


You can map data in VLANs to an instance and configure the instance to the protected VLAN so that the device can control data in VLANs based on RRPP.


  1. Run:


    The system view is displayed.

  2. Run:

    stp region-configuration

    The MST region view is displayed.

  3. Run:

    instance instance-id vlan { vlan-id1 [ to vlan-id2 ] }&<1-10>

    The mapping between the instance and VLAN is configured.

    instance-id in this command must be the same as instance-id used by the protected-instance command.


    The control VLANs of the major ring and the sub-rings must be contained in the VLAN list.

    To configure the mapping between the instance and MUX VLAN, you are advised to configure the principal VLAN, and subordinate group VLANs and subordinate separate VLANs of the MUX VLAN in the same instance. Otherwise, loops may occur.

    If the stp mode (system view) command is used to configure the switch to work in VBST mode, the static instance protected by RRPP cannot be directly deleted.

    Instance 0 is the default instance and does not need to be created.

    By default, all VLANs are mapped to Instance 0.

  4. Run:

    active region-configuration

    The configuration of the MST domain is activated.
