Read that book while ago, still it does not give us any insights on how
some of the largest OSPFareas/networks in the world look like.

As I think priscilla pointed out, Ciscopress has a book called Advanced IP
Network Design, which gives one of the best explainations of deploying a
large OSPF network.

Brian,
I am pretty sure there is no easy answer for my question. That is why I am
more interested in you guys experience, if somebody says an OSPF area should
not be larger than 50 routers(I read this from some books) and one of us
jumps up and say I have designed one with 1000 routers in one are

I have been told that Cisco has many customers who have large OSPF networks
with as many as 50 routers per area. (50 is the number Cisco uses as a
recommended max. Of course the real answer is "it depends," as others have
said.)
You might want to take a look at the OSPF section in Cisco's "Des
It's not really the number of routers in Area 0 that is the big deal, it's
the amount of memory for area 0 that each router must support for all the
routes for your scenario. Are you planning on having a lot of stub routers?
Or do you want to equip all your routers with 128Mb+ worth of DRAM?

Their are no hard and fast rules to answer questions like this. How are
the remotes connected? What type of media/speed?
do the remotes have other external connectivity other than the link to
area0? do any of the remotes inject external routes (redistributing from
other protocols)?

We are trying to design an OSPF network for one of our clients who has about
300 routers.
About 60 of them are in the Centeral Office, the rest of them are all
remotes.
We are thinking of put the 60 routers in the centeral into Area 0 and also
put some of the remote ABRs into Area 0 too.
