NAME

       dhcp6c.conf - configuration file of the DHCPv6 client daemon, dhcp6c

DESCRIPTION

       dhcp6c.conf is a configuration file for dhcp6c (DHCPv6 client).

       dhcp6c  is  configured by the configuration information (such as rapid-commit, requesting temp-address, or prefix-delegation) in this file.
       dhcp6c.conf is an ASCII text file and lines that start with # are comments.

STATEMENTS

       interface <interface name>
       {
	    [declarations]
       };

       Write configurations for this interface in this statement.  In [declarations], options can be specified.

DECLARATIONS

       send [dhcpoptions];

       With this declaration, dhcp6c sends specified options.  Currently rapid-commit is defined.

       send rapid-commit;
       This declaration enables dhcp6c to request the dhcp6s server to perform a Rapid Commit.

       request [dhcpoptions];
       This declaration enables dhcp6c to request specified options.   Currently  temp-address,  domain-name-servers,  and  prefix-delegation  are
       defined.

       request domain-name-servers;
       The DHCPv6 mechanism provides a way to obtain configuration information such as a list of available DNS servers or NTP servers. This decla-
       ration enables dhcp6c to request a DNS server address from the DHCPv6 server.

       request domain-search-list;
       This declaration enables dhcp6c to request a domain search list which dhcp6c uses when resolving hostnames with DNS.

       request prefix-delegation;
       This declaration enables dhcp6c to request a Prefix Delegation to the DHCPv6 server. dhcp6c  gets  a  prefix  assignment  from  the  DHCPv6
       server.

       request temp-address;
       This  declaration  enables  dhcp6c  to  request temporary addresses.  dhcp6c requests Non-temporary Addresses as default. This option makes
       dhcp6c request Temporary Addresses.

       information-only;
       This declaration enables dhcp6c to request host configuration information from the DHCPv6 server. If dhcp6c doesn't need to be assigned any
       addresses, this option should be specified.

       default-information-refresh-time <information refresh time>;
       This  declaration  defines the default interval to refresh the host configuration information retrieved from a server. When a server offers
       an interval to dhcp6c, dhcp6c chooses the interval from server. If this declaration is  not  specified,	the  interval  is  86400[sec]  (24
       hours). The minimum interval is 400[sec]. If you don't want to refresh the information, specify infinity as the interval.

       maximum-information-refresh-time <information refresh time>;
       This  declaration  defines  the	maximum interval to refresh the host configuration information retrieved from a server. When DHCPv6 server
       offers an interval which is bigger than this maximum interval, dhcp6c chooses this maximum interval.  If this declaration is not specified,
       dhcp6c uses the interval which a server offered or the interval which is specified at default-information-refresh-time declaration.

       address {
	    [<ipv6 address>/<prefix length>];
	    [prefer-life-time <preferred-lifetime>];
	    [valid-life-time <valid-lifetime>];
       };
       This  declaration  defines the dhcp6c client preferred IPv6 address, the preferred lifetime of the address, and the valid lifetime for this
       interface.

       prefix {
	    [<ipv6 prefix>/<prefix length>];
	    [prefer-life-time <preferred-lifetime>];
	    [valid-life-time <valid-lifetime>];
       };
       This declaration defines the dhcp6c client acting as a requesting router for the preferred prefix, the prefix length, and the prefix's pre-
       ferred lifetime, and valid lifetime for this interface.

       prefer-life-time <preferred-lifetime>;
       This  declaration  sets	the  preferred lifetime (in seconds) of the address or prefix. This declaration is valid only in address or prefix
       declarations.

       valid-life-time <valid-lifetime>;
       This declaration sets the valid lifetime (in seconds) of the address or prefix.	This declaration is valid only in address or prefix decla-
       rations.

       renew-time <renew-time>;
       This declaration specifies the Renew Time (in seconds) for this Identity Association (IA). Renew Time is a T1 value in an IA option. dhcp6c
       sets the Renew Time in IA options to the specified value.

       rebind-time <rebind-time>;
       This declaration specifies the Rebind Time (in seconds) for this IA. Rebind Time is T2 value in an IA option. dhcp6c sets the  Rebind  Time
       in IA options to the specified value.

DHCPOPTIONS

       rapid-commit
       If this option is used in a "send [dhcpoptions];" declaration, dhcp6c sends DHCPv6 messages with a Rapid Commit option.

       domain-name-servers
       If this option is used in a "request [dhcpoptions];" declaration, dhcp6c requests the DNS server address via the DHCPv6 mechanism.

       prefix-delegation
       If this option is used in a "request [dhcpoptions];" declaration, dhcp6c requests a Prefix Delegation to the DHCPv6 servers.

       prefix-delegation-interface <interface name>
       Specifies the name of the interface definition in radvd.conf
       that dhcp6c will write the 'prefix' declaration for. By default,
       dhcp6c will write a radvd.conf prefix declaration for the interface
       on which it receives the prefix delegation lease.

EXAMPLES

       This is a sample of the dhcp6c.conf file.
       interface eth0 {
	    send rapid-commit;
	    request prefix-delegation;
	    request domain-name-servers;
	    request temp-address;
	    iaid 11111;
	    address {
		 3ffe:10::10/64;
		 prefer-life-time 6000;
		 valid-life-time 8000;
	    };
	    renew-time 11000;
	    rebind-time 21000;
       };
