Enabling RRPP Snooping

Enabling RRPP Snooping


When RRPP snooping is enabled on an interface, the status of the RRPP ring can be detected through RRPP control packets. When the status of the RRPP ring changes, the interface requests the VSI bound to the interface to update its MAC address table.


RRPP and RRPP snooping cannot be simultaneously configured on the same interface.

Configure RRPP snooping only on the node connecting the RRPP ring to the VPLS network.


  1. Run system-view

    The system view is displayed.

  2. Entering the view of the interface to be enabled with RRPP snooping using the following commands as required

    • Run interface interface-type interface-number.subinterface-number

      The sub-interface view is displayed.

    • Run interface vlanif vlan-id

      The VLANIF interface view is displayed.

    Specifying that the sub-interface or VLANIF interface permits only the packets in the control VLAN of the RRPP domain to pass through.

  3. Run rrpp snooping enable

    RRPP snooping is enabled.

    Before running this command, bind the sub-interface or VLANIF interface to the VSI.

    If the sub-interface or VLANIF interface is removed from the VSI, RRPP snooping is automatically disabled on the interface.

    After RRPP snooping is enabled on the sub-interface or VLANIF interface, the sub-interface or VLANIF interface is automatically associated with the VSI.

    By default, RRPP snooping is disabled.
