Configuring a QinQ VLAN Tag Termination Sub-interface

Configuring a QinQ VLAN Tag Termination Sub-interface


A QinQ VLAN tag termination sub-interface can terminate double-tagged user packets. Perform the following operations on a user-side interface of a PE.


  1. Run system-view

    The system view is displayed.

  2. Run interface { ethernet | gigabitethernet } interface-number.subinterface-number

    The Ethernet sub-interface view is displayed.

  3. Run ip binding vpn-instance vpn-instance-name

    A VPN instance is bound to the sub-interface.

  4. Run ip address ip-address { mask | mask-length } [ sub ]

    An IP address is configured for the Ethernet sub-interface.


    When two or more IP addresses are configured for an Ethernet interface, use sub to specify the second IP address and subsequent IP addresses.

  5. Run qinq termination pe-vid pe-vid ce-vid ce-vid1 [ to ce-vid2 ]

    The sub-interface is configured to terminate double-tagged packets.

    • high-pe-vid is supported by only the AR3200-S.

    • You can specify high-pe-vid only after the termination-vid batch enable command is used to enable a sub-interface to batch terminate VLAN tags.

    • The value of high-pe-vid must be greater than or equal to the value of low-pe-vid.

    • When this command is executed on an Eth-Trunk sub-interface, you cannot specify high-pe-vid.

    • After a VLAN tag termination sub-interface is configured, ensure that ARP broadcast is enabled on the sub-interface. For details, see the arp broadcast enable command.
