I work with a large OSPF Network with over 57'000 clients. This network is a star network utilising area 0 at the core. The sub area's are based on what we call clusters which are the way the sites are brokens down. These clusters are given sections of the IP Address subnetting, this provides a convienient point for summarizing the address space.

  Hello folks,

Being that my OSPF experience is limited to small environments with one area
(area 0) I would like to know how big companies do OSPF.
For example, when would they decide to create multiple areas?
How do they usually assign areas - by geographic area, by department, by
function?
Are virtual links common practice in the real world?

Thanks
