OSPF totally stub area maximum router support

[nqureshi]

How many maixmum routers can an ospf totally stub area can support keeping in mind new range routers such as 1700 series router as spoke and 3661 as hub router.

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.
