Hi Michael,

ospf6d doesn't support multiple areas yet:

BUGS
     Virtual links are currently not available in ospf6d.

     Support for multiple areas is currently not available in ospf6d.

There might be a routing hackathon this year (Claudio will know more).
If that happens and I can manage to attend, I'd be interested to look
into multi-area support for ospf6d.

Cheers,
Stefan
