Re: largest OSPF core

I think it is really depending on how your network topology looks like.
If you have top-down design with star topology to limit the network
connections to individual routers, it may scale well.
But if you connect every routers to each other such as full-mesh, it
will be a problem during interface flapping or something like that.

I'll admit to having seen a network with over 400 devices in an
OSPF area 0, didn't design it, and in the end didn't get to work
on it.

Far as I know worked just fine though, no issues reported.  How
well your IGP scales depends a lot more on what you put in it, and
how dynamic your network situation is than the protocol or number
of devices.
