rad
is an IPv6 router advertisement
daemon. It periodically sends IPv6 router advertisement messages with prefix
and default router informations. 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.
rad
is usually started at boot time, and
can be enabled by setting the following in
/etc/rc.conf.local:
rad_flags=""
See rc(8) and rc.conf(8) for more information on the boot process and enabling daemons.
A running rad
can be controlled with the
ractl(8) utility.
The options are as follows:
-d
