NAME

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

 

DESCRIPTION

dhcp6c.confis 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 aRapid Commit.

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

request domain-name-servers;
The DHCPv6 mechanism provides a way to obtain configuration informationsuch as a list of available DNS servers or NTP servers. This declarationenables 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 whichdhcp6c 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 makesdhcp6c request Temporary Addresses.

information-only;
This declaration enables dhcp6c to request host configuration informationfrom 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 configurationinformation 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 youdon'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 configurationinformation retrieved from a server. When DHCPv6 server offers an interval whichis bigger than this maximum interval, dhcp6c chooses this maximum interval.If this declaration is not specified, dhcp6c uses the interval which a serveroffered or the interval which is specified at default-information-refresh-timedeclaration.

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 thisinterface.

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

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

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

rebind-time <rebind-time>;
This declaration specifies the Rebind Time (in seconds) for this IA. RebindTime is T2 value in an IA option. dhcp6c sets the Rebind Time in IA optionsto 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 interfaceon 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;};
