Configuring a Dynamic Profile Used to Create Single-Tag VLANs

 

Starting in Junos OS Release 14.1, you can configure a dynamic profile for creating single-tagged VLANs.

Before you begin:

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 (Dynamic Profiles) statement.
  4. Specify that you want to use dynamic VLAN IDs in the dynamic profile. You can configure the dynamic profile to create a single-tag VLAN using only standard tag protocol identifier (TPID) values (0x8100) or to create a VLAN using any TPID value.

    • To configure the dynamic profile to create single-tag VLANs that accept only standard TPID values (a TPID value of 0x8100):

      When the dynamic profile is instantiated, the variable is dynamically replaced with a VLAN ID within the VLAN range specified at the [interfaces] hierarchy level.

    • To configure the dynamic profile to create single-tag VLANs that accept any TPID value:

      The variable is dynamically replaced with both the TPID value and a VLAN ID within the VLAN range specified at the [interfaces] hierarchy level.

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