Hello,

 

in a real network, what are the pros and cons of using OSPF areas ?

 

I see the following pros:

*	reduced routing tables (visually when doing a 'sh ip ro', and in
RAM) thanks to summarisation
*	reduced CPU usage since route flaps are not seen outside of the area

 

and the following con: additional complexity.

 

Did I forget something?

 

Vincent
