• The client may have other addresses in other IAs, so the client can discard the expired IA and use
the addresses in the other IAs.
The client sends a RELEASE message to release an IA. This message is sent to the server that assigned the
addresses to the client initially and the client will wait until the timeout value expires. If the server cannot
be reached after 5 attempts, the client will abandon this release attempt. These addresses will be claimed
by the servers when the lifetimes of the addresses expire.
The administrator will trigger
dhcpv6d to unicast a RECONFIGURE-INIT message to all those clients
who have their addresses assigned by this server when the server configuration changes are vital. This
message is a trigger which will cause the clients to initiate a standard REQUEST message to the server to
obtain the new or updated configuration parameters.
Configuration File
Upon startup,
dhcpv6d reads the configuration file,
/etc/dhcpv6tab, or a file specified with the
-c
option to build its internal database and then listens for SOLICIT/REQUEST messages from the client. If
configuration parameters are added, deleted, or modified, then their entries in the internal database are
updated when dhcpv6d is invoked with the
-r option.
The configuration file contains the following sections:
1. DHCPv6 client Default settings
2. DHCPv6 pool group settings
3. DHCPv6 relay settings
Blank lines and lines beginning with "#" in the configuration file are ignored. Entries are separated from
one another by a semicolon. Multiple entries of a group can be extended over multiple lines if the lines end
with a backslash \. A final semicolon ; followed by a new line indicates the end of a group.
IP addresses are specified in the standard IPv6 notation (colon notation) and can use hexadecimal numbers.
The tags for the DHCP_CLIENT_DEFAULT_SETTINGS are as listed below. These tags are applicable to
all the addresses that the server assigns to the DHCPv6 client.
client-settings-name=
client-settings-name-in-string-format
;
This tag specifies the name of the group default settings.
POSIX-time-zone=
POSIX-time-zone-string;
This tag specifies the POSIX time zone of the client. This should be as per the
IEEE 1003.1 format.
DNS-server-address=
List-of-IP-addresses-in-IPv6-Address-Format
;
This tag specifies the list of DNS nameservers available to the client. Multiple
nameserver addresses are separated by white spaces.
DNS-suffix= string-format;
This tag specifies the default domain name suffix that the client should use while
resolving hostnames via DNS.
NIS-domain-name=
string-format;
This tag specifies the name of the client’s NIS domain. The NIS-domain-name is
formatted as a character string consisting of characters from the NVT-ASCII
character set.
NIS-server-address=List-of-IP-addresses-in-IPv6-Address-Format
;
This tag specifies the list of NIS servers available to the client. Servers SHOULD
be listed in the order of their preference.
NIS+client-domain-name=string-format
;
This tag specifies the name of the client’s NIS+ domain. The domain is formatted
as a character string consisting of characters from the NVT-ASCII character set.
NIS+server-address=List-of-IP-addresses-in-IPv6-Address-Format
;
This tag specifies the list of NIS+ servers available to the client.
NTP-server-address=List-of-IP-addresses-in-IPv6-Address-Format;
This tag specifies the list of NTP servers available to the client.
SLP-DA-address=list-of-DA-addresses-followed-by-their-scope-list;
This tag specifies the list of SLP Directory agents available to the client. The
