NAME
     rad -- router advertisement daemon

SYNOPSIS
     rad [-dnv]	[-f file] [-s socket]

DESCRIPTION
     rad is an IPv6 router advertisement daemon.  It periodically sends	IPv6
     router advertisement messages with	prefix and default router information.
     Clients like slaacd(8) use	these to configure IPv6	addresses on network
     interfaces	and set	default	routes.	 Additionally it listens for IPv6
     router solicitation messages and responds with router advertisements.

     To	have rad enabled at boot time, use "rcctl enable rad", which sets

	   rad_flags=""

     in	rc.conf.local(8).

     A running rad can be controlled with the ractl(8) utility.

     The options are as	follows:

     -d	     Do	not daemonize.	If this	option is specified, rad will run in
	     the foreground and	log to stderr.

     -f	file
	     Specify an	alternative configuration file.

     -n	     Configtest	mode.  Only check the configuration file for validity.

     -s	socket
	     Use an alternate location for the default control socket.

     -v	     Produce more verbose output.

FILES
     /etc/rad.conf	  Default rad configuration file.
     /var/run/rad.sock	  UNIX-domain socket used for communication with
			  ractl(8).
