The stupidity of trying to "fix" DHCPv6

For my future ipv6 server network I tried to go without ra - but ran into 
troubles.
I use ucarp from freebsd for the ipv4 servers to have a failover gateway - 
but this does not work because of dad.
So I have now a ip for each gateway, still failover via ucarp to bring the 
interface up / down and advertise the active default gw via ra.
