Re: OSPF Backbone Area Clarification

Then maybe because Area 0 is defined as backbone are in the RFC2328 ?
https://www.ietf.org/rfc/rfc2328.txt

Area 0 correspond also to area 0.0.0.0 (depending how you write it) and
it's the lowest ID for an area.

This is how the protocol was developed in my opinion. I'm for sure not
smarter than those who develop the protocol, but I believe they have
chose the lowest possible ID to be the backbone area to avoid confusion
in protocol functionality.

Cheers,
Calin
