Indicates whether leases using this policy are permanently granted
to requesting clients. If leases are permanently granted,
the dhcp-lease-time will be "infinite."
preferred-lifetime time default = 1w
Assigns the default and maximum preferred lifetime for leases to
DHCPv6 client interfaces. Expressed in seconds and relative to
the time the server sent the packet, this attribute sets the
length of time that the address is preferred; that is, its use is
unrestricted. When the preferred lifetime expires, the address
becomes deprecated and its use is restricted.
reconfigure enumint(allow=1, disallow=2, require=3) default = allow
Controls DHCPv6 client reconfiguration support:
1 allow Allows clients to request reconfiguration
support and the server will honor the
request (default).
2 disallow Allows clients to request reconfiguration
support but the server will not honor
the clients' request.
3 require Requires clients to request reconfiguration
support and the server drops client
Solicit and Request messages that do not
include a Reconfigure-Accept option.
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
as follows:
- If any of the prefix policies has this attribute set to
disallow or require, that setting is used.
- Otherwise, if at least one has it set to allow, Reconfigure
is allowed.
- If no prefix policies have this attribute set, the remaining
policies in the hierarchy are checked.
reconfigure-via-relay bool default = false
Controls whether the server should prefer unicasting or
relaying DHCPv6 Reconfigure messages.
If false (the default), the server prefers to unicast
Reconfigure messages if the client has one or more valid
statefully assigned addresses.
If true, the server prefers to send Reconfigure messages
via the relay agent unless no relay agent information is
available.
Note: When you use this attribute, consider that:
- In networks where the DCHPv6 server cannot communicate
directly with its client devices?for example, where
firewalls are in place?set this value to true.
- The DHCPv6 server does not use embedded and named
policies configured on a client when it evaluates
this attribute.
- The relay agent cannot be used if the Relay-Forw message
