This feature is designed to simulate various access line attributes defined by the Broadband Forum,
|
|
which are subsequently employed in protocols such as PPPoE discovery, DHCPv4, and DHCPv6 packets.
|
|
|
|
The values defined in **access-line** section apply globally but can be overwritten in the
|
|
access interface section. The strings agent-remote-id, agent-circuit-id, and
|
|
access-aggregation-circuit-id support :ref:`variable substitution <variables>`.

Attributes with values set to zero will be automatically excluded,
|
|
making it impossible to send attributes with a zero value. In other words,
|
|
any attribute that has a value of zero will not be included in the corresponding
|
|
packets.
|
|
|
|
In the context of DHCPv6, access line attributes, as well as Agent-Remote-Id or Agent-Circuit-Id,
|
|
are exclusively permitted in DHCPv6 relay-forward messages as dictated by RFC. By default, BNG Blaster
|
|
includes these attributes in other DHCPv6 messages, even if this deviates from RFC guidelines.
|
|
Therefore, the DHCPv6 configuration section provides the option to either disable access-line attributes or,
|
|
as an alternative, enable LDRA (Lightweight DHCPv6 Relay Agent). |
