.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} dhcpv6-options duid <duid>
**Configure a specific** :abbr:`DUID (DHCP Unique Identifier)` **for the
DHCPv6 client on this interface.**
The DUID is an identifier used by a DHCPv6 client to get an IPv6 address from
a DHCPv6 server. It consists of a 2-byte type field, followed by a
variable-length identifier field up to 128 bytes. The format of the identifier
part depends on the DUID type:
* **DUID-LLT:** The most common type, which includes a hardware type, a timestamp, and a MAC address.
* **DUID-EN:** Is based on a vendor's enterprise number and a unique identifier assigned by the vendor.
* **DUID-LL:** Includes only a MAC address.
The DHCP server matches the DUID against its database and provides
configuration data (such as address, lease times, DNS servers, etc.)
to the DHCP client.
Example:
.. code-block:: none
set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} {{ var5 }} {{ var7 }} duid '0e:00:00:01:00:01:27:71:db:f0:00:50:56:bf:c5:6d'
.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} dhcpv6-options no-release
**Configure the DHCP client not to send a release message when it stops
running on this interface.**
This helps retain the assigned address or prefix.
Example:
.. code-block:: none
set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} {{ var5 }} {{ var7 }} dhcpv6-options no-release
.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} dhcpv6-options parameters-only
**Enable a stateless DHCPv6 client mode on this interface.**
In stateless mode, the DHCPv6 client requests only stateless configuration
parameters from the DHCP server (for example, DNS server addresses). It
doesn’t request a stateful configuration, such as IPv6 addresses or prefixes.
Example:
.. code-block:: none
set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} {{ var5 }} {{ var7 }} dhcpv6-options parameters-only
.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} dhcpv6-options rapid-commit
**Enable DHCPv6 rapid commit on this interface.**
When enabled, the DHCP client and server skip the negotiation steps
(Advertise and Request), completing the DHCPv6 configuration process
in just two messages (Solicit and final Reply).
Example:
.. code-block:: none
set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} {{ var5 }} {{ var7 }} dhcpv6-options rapid-commit
.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} dhcpv6-options temporary
**Configure the DHCPv6 client to request a temporary IPv6 address on this
interface.**
When configured, the DHCP client doesn’t form an Identity Association for
Non-temporary Addresses (IA_NA) partnership. Consequently, it only obtains
a temporary IPv6 address and doesn’t obtain a permanent one.
Example:
.. code-block:: none
set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} {{ var5 }} {{ var7 }} dhcpv6-options temporary
