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
