OSPF

OSPF Area 0 is a backbone area. Other Area must connect to Area 0.
Virtual link use for connect to Area 0 pass from other area.

OSPF Stub

The following restrictions apply to stub areas:     You cannot create a virtual link through a stub area.   A stub area cannot contain an AS boundary router.   You cannot configure the backbone as a stub area.   You cannot configure an area as both a stub area and an not-so-stubby area (NSSA).
