Configuring VLANs for the DHCPv6 Layer 3 Wholesale Network Solution

You can configure either static or dynamic customer VLANs for use in the DHCPv6 wholesale network solution.

Configuring Static Customer VLANs for the DHCPv6 Layer 3 Wholesale Network Solution

In this example configuration, the access interface (ge-2/3/0) connects to a device (that is, a DSLAM) on the access side of the network. You can define static VLANs for use by access network subscribers.

To configure the static VLANs:

  1. Edit the access side interface.

  2. Specify the use of stacked VLAN tagging.

  3. Edit the interface unit for the first VLAN.

  4. Define the VLAN tags for the first VLAN.

  5. Specify that you want to create IPv6 demux interfaces.

  6. Edit the family for the first VLAN.

  7. (Optional) Define the unnumbered address and the preferred source address for the first VLAN.

  8. Repeat steps 2 through 7 for additional VLAN interface units.

Configuring Dynamic Customer VLANs for the DHCPv6 Layer 3 Wholesale Network Solution

To configure dynamic VLANs for the solution:

  1. Configure a dynamic profile for dynamic VLAN creation.
    1. Name the profile.
    2. Define the interfaces statement with the internal $junos-interface-ifd-name variable used by the router to match the interface name of the receiving interface.
    3. Define the unit statement with the predefined $junos-interface-unit variable:
    4. Specify that you want to create IPv6 demux interfaces.
    5. Specify the VLAN ID variable.

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

    6. 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.

    7. Access the family type.
    8. (Optional) Specify the unnumbered address and preferred source address.
  2. Associate the dynamic profile with the interface on which you want the VLANs created.
    1. Access the interface that you want to use for creating VLANs.
    2. Specify the use of stacked VLAN tagging.
    3. Specify that you want to automatically configure VLAN interfaces.
    4. Specify that you want to configure stacked VLANs.
    5. Specify the dynamic VLAN profile that you want the interface to use.
    6. Repeat steps a through e for any other interfaces that you want to use for creating VLANs.
  3. Specify the Ethernet packet type that the VLAN dynamic profile can accept.
  4. Define VLAN ranges for use by the dynamic profile when dynamically creating VLAN IDs. For this solution, specify the outer and inner stacked VLAN ranges that you want the dynamic profile to use. The following example specifies an outer stacked VLAN ID range of 3–3 (enabling only the outer range of 3) and an inner stacked VLAN ID range of 1–3 (enabling a range from 1 through 3 for the inner stacked VLAN ID).
