Hello

First some OSPF area hints:

1. rule of OSPF areas: Don't use it unless you know exactly what are you doing.

2. rule of OSPF areas: If you still want to use it, stick to stub and NSSA areas
   and avoid transit areas and especially vlinks. Just change transit areas
   to the backbone.

Thanks for the bugreport, i will fix it, it is pretty straightforward.
As you are probably the first who tried to use vlinks in OSPFv3, expect
some unexpected behavior ;-) .
