Guys,
From your excellent experience, what do you recommend in hub and spoke
topology for ATM, to use one Flat network for the whole WAN links between
hub and spokes, or to go subinterfaces and each link has its own network
/252 links. I will be running OSPF Area 0 on the Wan links between the Hub
and the spokes.
Both of them will work, but my concern is performance and easy of management
and scalability for the future.
I think one Flat ATM WAN network will be better.So who are with and who are
against?
