Configuring a Dynamic Profile Used to Create Stacked VLANs

Before you begin:

Starting in Junos OS Release 14.1, you can configure a dynamic profile for creating stacked 802.1Q VLANs.

To configure a dynamic VLAN profile:

  1. Ensure that the VLAN dynamic profile uses the $junos-interface-ifd-name variable for the dynamic interface and the $junos-interface-unit variable for the interface unit.
  2. (Optional) To support dynamic demux interfaces, enable them for IPv4 or IPv6.

    • For IPv4 demux interfaces:

    • For IPv6 demux interfaces:

  3. (Optional) To configure the router to respond to any ARP request, specify the proxy-arp statement.
  4. Specify the outer VLAN ID variable.

    The variable is dynamically replaced with an outer VLAN ID within the VLAN range specified at the [interfaces] hierarchy level.

  5. Specify the inner VLAN ID variable.

    The variable is dynamically replaced with an inner VLAN ID within the VLAN range specified at the [interfaces] hierarchy level.

  6. Define the unit family type.
    1. For IPv4 interfaces:
    2. For IPv6 interfaces:
  7. (Optional) Enable IP and MAC address validation for dynamic demux interfaces in a dynamic profile.
  8. Specify the unnumbered address and preferred source address.
