Configuring Tagged Interface with multiple tagged vlans and native vlan

You can configure the router to receive and forward single-tag frames, dual-tag frames, or a mixture of single-tag and dual-tag frames.

  1. To configure the router to receive and forward single-tag frames with 802.1Q VLAN tags, include the vlan-tagging statement at the [edit interfaces interface-name] hierarchy level:
  2. Configure the flexible-vlan-tagging statement at the [edit interfaces ge-fpc/pic/port] hierarchy level.

    For encapsulation type flexible-ethernet-services, all VLAN IDs are valid.

  3. To accept untagged packets, include the native-vlan-id statement and the flexible-vlan-tagging statement at the [edit interfaces interface-name] hierarchy level:

    The range for native-vlan-id is 0 to 4094.

    The logical interface on which untagged packets are to be received must be configured with the same native VLAN ID as that configured on the physical interface. To configure the logical interface, include the vlan-id statement (matching the native-vlan-id statement on the physical interface) at the [edit interfaces interface-name unit logical-unit-number] hierarchy level.

  4. Configure the vlan-id range providing the range at the [edit interfaces ge-fpc/pic/port unit logical-unit-number] hierarchy level:
  5. Configure the vlan-tags statement with inner and outer options or the vlan-id range statement at the [edit interfaces ge-fpc/pic/port unit logical-unit-number] hierarchy level:

    The range for inner and outer option 32 to 4094.

To verify the configuration execute the show command.
