Configuring the Server
This section describes how to configure the DHCPv6 server.
It discusses the following topics:
“The dhcpv6d Server Daemon” (page 127)
“Server Configuration File” (page 128)
“Setting Up the DHCPv6 Server” (page 128)
“Sample dhcpv6tab File” (page 129)
The dhcpv6d Server Daemon
dhcpv6d is the IPv6 version of bootpd that runs as a standalone daemon. The dhcpv6d daemon
supports the following features:
Dynamic renumbering
Relay preconfiguration with server addresses or use of multicast addresses
Multiple IP addresses for an interface
You can start dhcpv6d by one of the following methods:
Invoking dhcpv6d from the command line.
Editing the /etc/rc.config.d/netdaemons file to invoke dhcpv6d upon each reboot.
Invoking dhcpv6d
To invoke dhcpv6d, run the following command on the command line:
/usr/sbin/dhcpv6d [-d] [-c config_file] [-k]
[-h] [-r] [-u] [-C] [-R]
where,
-d
Enables debugging.
-c config_file
Specifies the alternate configuration file to be read by the DHCPv6
server. The default file is /etc/dhcpv6tab.
-k
Kills the server gracefully.
h max_hop_count
Specifies the maximum number of hops allowed for a DHCPv6 packet
after which the server drops the DHCPv6 packet.
-r
Rereads the configuration file and triggers the server to send a
reconfig-init message to the clients when the configuration file
has any new or updated information.
u
Enables the unicast option.
C
Enables the rapid commit option.
R
Runs the DHCPv6 server as a relay agent.
