Re: OSPF Backbone Area Clarification

The backbone Area, or Area 0, is treated specially, and handles LSAs
differently from other standard Areas. if you had multiple routers in your
network with different views of what the backbone area is, you could get
routing loops. I suppose (technically) a vendor could decide to designate
the backbone area to some other value, other than 0.0.0.0, but this would
cause a lot of interoperability issues. This is why vendors try to follow
the RFC.
