OSPF only required an area 0 if there is more than 1 area... you can
build your network with area 555 (and only area 555) and be good to
go.... then when you are ready to merge, just hook up to their area 0...
No prob.

Subject: Can you have OSPF without area 0 at all?
Team,
I came across an interesting finding. I want to take everybody's opinion
on this before putting anything in production. We are building an OSPF
network that will eventually merge with company's main OSPF backbone
network. The core group has assigned us ospf area number 555.
When I configure all my routers with OSPF area 555(with no area 0 at
all), it seems to be building up routing table. I always thought OSPF
needs area 0 to function. Will this work of we add a non cisco device
with area 555 configuration?
What is the catch 22 in this configuration? I have started reading OSPF
RFC to figure out all technical details.
Thanks,
Sam Munzani
