Well Shadi, That depends on the size of your network. If you believe that
you can run one flat network without congestion and you don't mind one
problem on a link bringing the whole network down because it is all one bit
flat layer 2/3 network then that should be fine. If you have few users, no
worries about broadcast storms/spanning tree problems affecting the network
then go that way. It will work either way but the type/size of your network
is the determining factor here....Bob
