Configuring OSPFv3 Area Parameters

The stub area and virtual link features of OSPFv3 are the same as OSPFv2.
Splitting an OSPFv3 AS into multiple areas reduces the number of LSAs and extends OSPFv3
applications. For those non-backbone areas residing on the AS boundary, you can configure them as
stub areas to further reduce the size of routing tables and the number of LSAs.
Non-backbone areas exchange routing information via the backbone area. Therefore, the backbone
and non-backbone areas, including the backbone itself must be contiguous. In practice, necessary
physical links may not be available for such connectivity. You can configure virtual links to address the
problem.
