Configuring Dynamic VLANs Based on Access-Line Identifiers

date_range 06-Dec-23

You can configure dynamic VLAN subscriber interfaces for DHCP and PPPoE subscribers based on the access-line identifier (ALI). These subscriber interfaces are also known as access-line identifier VLANs, ALI-based dynamic VLANs, or ALI dynamic VLANs. To configure these VLANs, you create an ALI interface set, which is a logical collection of subscriber interfaces that originate at the same household or on the same access-loop port, and then you reference the ALI interface set in the dynamic profile for a PPPoE or IP demultiplexing (IP demux) logical subscriber interface.

To configure a dynamic VLAN subscriber interface based on the ALI:

  1. Configure a dynamic profile that defines the dynamic ALI interface set.
  2. (Optional) In the dynamic profile for the ALI interface set, configure the router to use the Actual-Data-Rate-Downstream VSA [26-130] or Access-Loop-Encapsulation VSA [26-144] value in PPPoE control packets to adjust CoS shaping-rate and overhead-accounting attributes at a per-household level.
  3. Dynamically or statically configure the underlying VLAN logical interface to enable dynamic subscriber interface creation based on the ALI.
  4. Associate the dynamic ALI interface set with the dynamic PPPoE or dynamic IP demux logical subscriber interface.
  5. (Optional) In the dynamic profile for the PPPoE (pp0) subscriber interface, configure the router to use the Actual-Data-Rate-Downstream VSA [26-130] or Access-Loop-Encapsulation VSA [26-144] value in PPPoE control packets to adjust CoS shaping-rate and overhead-accounting attributes at a per-subscriber level.
