NAME
dhcpv6d - Dynamic Host Configuration Protocol Server daemon for IPv6
SYNOPSIS
/usr/sbin/dhcpv6d
[-c config_file ][
-d][-h max_hop_count][
-u][-C][-R]
/usr/sbin/dhcpv6d -k
/usr/sbin/dhcpv6d -r
DESCRIPTION
The DHCPv6 server daemon is the IPv6 version of the bootpd daemon. This implementation of
dhcpv6d is based on the RFC 3315.
This version of
dhcpv6d supports the following features:
• Dynamic renumbering
• Relay preconfiguration with server addresses, or use of multicast addresses
• Multiple IP addresses for an interface
The
dhcpv6d daemon is run as a stand-alone daemon and not spawned by
inetd.
Options
-c config_file Specify an alternate configuration file for the server. The default configuration file
is /etc/dhcpv6tab.
-d Toggle debugging on or off.
-h max_hop_count Specify the maximum number of hops allowed for a DHCP packet after which the
server drops the DHCP packet.
-k Kill the server gracefully.
-r Re-read the configuration file and trigger the server to send a reconfig-init message
to the clients when the configuration file has any new or updated information.
-u Enable Unicast option.
-C Enable Rapid Commit option.
-R Run the DHCPv6 server as a relay agent.
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 DHCPv6 messages from the client.
The configuration file contains the following sections:
1. DHCPv6 client default settings
2. DHCPv6 pool group settings
3. DHCPv6 relay settings
4. DHCPv6 device group settings
5. DHCPv6 address pool settings
6. DHCPv6 relay interface mapping settings
7. DHCPv6 client duid (DHCP Unique Identifier) group 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 binary hexadecimal format of a tag can be represented with each byte separated by a colon (:) and
without ‘0x’ prefixed to the hexadecimal number.
For example: The tag
0x12a131469 can be represented as 1:2a:13:14:69.
