Re: OSPF totally stub area maximum router support

There is no hard number but a totally stubby configuration will make your area more scalable. Bare in mind that even though you won't be receiving inter area and external LSAs, you obviously still need ro run the SPF every time there is a change in the topology of the local area.

Incremental SPF would be one way:

Plus making certain that you have a little tpology change as possible, etc.
