Are you sure your network card is up when booting the system?
you can check /etc/sysconfig/network-scripts/ifcfg-eth0
to see
ONBOOT=yes or no?
You need to set it to yes so it will startup network card while booting.

In /etc/radvd.conf, it defines the prefix. So when sending RA it will anounce router's prefix to all the host connected to it.
