+.. cfgcmd:: set interfaces {{ var0 }} <interface> dhcpv6-options parameters-only
+
+  This statement specifies dhcp6c to only exchange informational configuration
+  parameters with servers. A list of DNS server addresses is an example of such
+  parameters. This statement is useful when the client does not need stateful
+  configuration parameters such as IPv6 addresses or prefixes.
+
+  Example:
+
+  .. code-block:: none
+
+    set interfaces {{ var0 }} {{ var1 }} dhcpv6-options parameters-only
+
+.. cfgcmd:: set interfaces {{ var0 }} <interface> dhcpv6-options rapid-commit
+
+  When rapid-commit is specified, dhcp6c will include a rapid-commit option in
+  solicit messages and wait for an immediate reply instead of advertisements.
+
+  Example:
+
+  .. code-block:: none
+
+    set interfaces {{ var0 }} {{ var1 }} dhcpv6-options rapid-commit
+
+.. cfgcmd:: set interfaces {{ var0 }} <interface> dhcpv6-options temporary
+
+  Request only a temporary address and not form an IA_NA (Identity Association
+  for Non-temporary Addresses) partnership.
+
+  Example
+
+  .. code-block:: none
+
+    set interfaces {{ var0 }} {{ var1 }} dhcpv6-options temporary
+
+
+
+
+**DHCPv6-PD**
+
+VyOS 1.3 (equuleus) supports DHCPv6-PD (:rfc:`3633`). DHCPv6 Prefix Delegation
+is supported by most ISPs who provide native IPv6 for consumers on fixed networks.
+
+.. cfgcmd:: set interfaces {{ var0 }} <interface> dhcpv6-option pd <id> length <length>
+
+   Some ISPs by default only delegate a /64 prefix. To request for a specific
+   prefix size use this option to request for a bigger delegation for this pd
+   `<id>`. This value is in the range from 32 - 64 so you could request up to a
+   /32 prefix (if your ISP allows this) down to a /64 delegation.
+
+   The default value corresponds to 64.
+
+  Example:
+
+  To request a /56 prefix from your ISP use:
+
+  .. code-block:: none
+
+    set interfaces {{ var0 }} {{ var1 }} dhcpv6-options pd 0 length 56
+
+.. cfgcmd:: set interfaces {{ var0 }} <interface> dhcpv6-option pd <id> interface <delegatee> address <address>
+
+   Specify the interface address used locally on the interfcae where the prefix
+   has been delegated to. ID must be a decimal integer.
+
+   It will be combined with the delegated prefix and the sla-id to form a
+   complete interface address. The default is to use the EUI-64 address of the
+   interface.
+
+   Example: Delegate a /64 prefix to interface eth0.10 which will use a local
+   address on this router of ``<prefix>::ffff``, as the address 65534 will
+   correspond to ``ffff`` in hexadecimal notation.
+
+  .. code-block:: none
+
+    set interfaces {{ var0 }} {{ var1 }} dhcpv6-option pd 0 interface eth0.10 address 65534
+
+.. cfgcmd:: set interfaces {{ var0 }} <interface> dhcpv6-option pd <id> interface <delegatee> sla-id <id>
+
+   Specify the identifier value of the site-level aggregator (SLA) on the
+   interface. ID must be a decimal number greater then 0 which fits in the
+   length of SLA IDs (see below).
+
+   Example: If ID is 1 and the client is delegated an IPv6 prefix
+   2001:db8:ffff::/48, dhcp6c will combine the two values into a single IPv6
+   prefix, 2001:db8:ffff:1::/64, and will configure the prefix on the specified
+   interface.
+
+  .. code-block:: none
+
+    set interfaces {{ var0 }} {{ var1 }} dhcpv6-option pd 0 interface eth0.10 sla-id 1

-Prefix Delegation (DHCPv6-PD)

-VyOS 1.3 (equuleus) supports DHCPv6-PD. DHCPv6 Prefix Delegation is supported

-
-   It will be combined with the delegated prefix and the sla-id to form a complete
-   interface address. The default is to use the EUI-64 address of the interface.

-   of SLA IDs (see below). For example, if ID is 1 and the client is delegated

-   single IPv6 prefix, 2001:db8:ffff:1::/64, and will configure the prefix on
-   the specified interface.
