Creating the L3VE Sub-interface Terminated by QinQ

If an L3VE sub-interface receives double-tagged service data packets from the UPE, configure the L3VE sub-interface as a sub-interface for QinQ VLAN tag termination to access the L3VPN.

Context

Do as follows on NPEs.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface virtual-ethernet interface-number interface-number

    A L3VE sub-interface is created the sub-interface view is displayed.

    You can create sub-interfaces only on the L3VE interface that operates in user termination mode.

  3. Run control-vid vid qinq-termination

    The sub-interface is encapsulated into the QinQ termination mode.

  4. Run qinq termination pe-vid pe-vid [ to high-pe-vid ] ce-vid ce-vid [ to high-ce-vid ] [ vlan-group group-id ]

    The QinQ termination is configured for the L3VE sub-interface.

    When the L3VE sub-interface receives packets with double tags from users, it will terminate the packets whose inner tag is in the range specified by the ce-vid.

  5. Run arp broadcast enable

    The ARP broadcast function is enabled for the sub-interface for QinQ VLAN tag termination.

    When you enable or disable the ARP broadcast function on a termination sub-interface, the routing status of the sub-interface becomes Down and then Up. This may result in a flapping of routes on the entire network, affecting the normal operation of services.

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

    The L3VE sub-interface is associated with a VPN instance.

  7. Run ip address ip-address { mask | mask-length }

    The IP address is configured.

    The IP address is a private network address of MPLS L3VPN.

  8. Run commit

    The configuration is committed.
