The router advertisement daemon (radvd) is run by Linux or BSD systems
acting as IPv6 routers. It sends Router Advertisement messages, 
specified by RFC 2461, to a local Ethernet LAN periodically and when 
requested by a node sending a Router Solicitation message. These 
messages are required for IPv6 stateless autoconfiguration.

Radvd is dependant upon IPv6 support in the Linux Kernel; this comes
enabled by default with Slackware 12's 'generic' kernel.  To enable
IPv6 support manually, you must set the following entry in your 
kernel's '.config' file and recompile:
	CONFIG_IPV6=m

Once the Slackware package is installed, edit /etc/radvd.conf to
reflect your current IPv6 configuration. 

An init script has been provided at /etc/rc.d/rc.radvd.  
To have radvd start at each boot, add the following lines to your
/etc/rc.d/rc.local file:
	# Start the radvd daemon:
	if [ -x /etc/rc.d/rc.radvd ]; then
	   /etc/rc.d/rc.radvd start
	fi
