Yup … have seen some *really* large networks run everything in backbone area …
In previous job, we had 6000+ routes in backbone area with no noticeable issues.

I have everything in area 0 too, and we've get well over 100 routers running OSPF and I really don't see any good reason to change it at this point.

Convergence time is fine so I see no reason to go to multi-area any time soon.

How big is too big for an OSPF database (At what point should one really start using areas)? With Mikrotik hardware, if there is no current need for VPLS tunnels or MPLS-TE, is there any benefit to running MPLS vs just OSPF? [I'm running it on some my network, and I'm debating whether to take the time to implement it everywhere.] Thanks - Chris
