Do you have tap0 configured in your /etc/radvd.conf file? If you want to send
it out a router advertisement, you'll need to have radvd running and
radvd.conf configured.

The ip command is the one to use if you need to set up static routes - see the
IPv6 HOWTO. You might also need to enable IPv6 forwarding in your kernel on
the host system.
