I'm moving my network from RIP to OSPF.
After reading documentation and examples I was confused what to put in backbone area. So I decided to skip backbone area.
Backbone area is disabled on all routers.
Now I have 8 routers in 4 areas and they exchange routes between each others without any problems. All documentation and examples (written for cisco) says that OSPF can't work without any problems. So what is wrong here ? How my network work without backbone area?
