Determines whether DHCPv6 clients can use a Solicit with the
Rapid Commit option to obtain configuration information with
fewer messages. To permit this, make sure that a single DHCP
server is servicing clients.
This attribute has special handling during the policy hierarchy
processing when checking the Prefix policies (embedded or named)
for the Prefixes on a Link. The Prefixes for the Link are
processed in alphabetic (case blind) order. For each Prefix, the
embedded and then named policy are checked. Only Prefixes to which
the client has access (based on selection tags, etc.) are checked:
- If any of the prefix policies has this attribute set to
FALSE, Rapid Commit is not allowed.
- If at least one has it set to TRUE, Rapid Commit is allowed.
- Otherwise, the remaining policies in the hierarchy are
checked.
The default is not to allow clients to use Rapid Commit.
allow-temporary-addresses bool default = true
Determines whether DHCPv6 clients can request temporary (IA_TA)
addresses.
The default is to allow clients to request temporary addresses.
default-prefix-length rangeint(0-128) default = 64
For delegation, specifies the default length of the delegated prefix,
if a router (client) does not explicitly request it.
The default length must always be less than or equal to the prefix
length of the prefix range.
forward-dnsupdate nameref(DnsUpdateConfig)
Specifies the name of the update configuration that determines
which forward zones to include in updates.
forward-zone-name dname
Designates an optional forward zone for DNS updates.
giaddr-as-server-id bool default = false
Enables the DHCP server to set the server-id option on a DHCPOFFER
and a DHCPACK to the giaddr of the incoming packet, instead of the
IP address of the server (the default action).
This causes all unicast renews to be sent to the relay agent instead
of directly to the DHCP server, and so renews arrive at the DHCP
server with option-82 information appended to the packet.
Some relay agents may not support this capability and, in some
complex configurations, the giaddr might not actually be an address
to which the DHCP client can send A unicast packet. In these cases,
the DHCP client cannot renew a lease, and must always perform a
rebind operation (where the DHCP client broadcasts a request instead
of sending a unicast to what it believes is the DHCP server).
grace-period time default = 5m
Defines the length of time between the expiration of a lease
and the time it is made available for reassignment.
inhibit-all-renews bool default = false
