Think of the MPLS VPN as a virtual network running on top of the service providers network. Unlike frame relay the VPN can not reach beyond the providers network (technically it is possible but I have not heard of any providers offering this at this point) which may or may not be a concern depending on the provider and the locations you need to connect. http://www.cisco.com/warp/public/732/Tech/mpls/ > scaleable Depends on who you listen to:) From the client perspective adding additional sites and increasing bandwith should not be an issue. > reliable Will be as reliable as the circuits/provider. > secure Although your traffic shouldn't be visible to the providers other customers it is not encrypted by the service provider.

There are a number of providers that indicate they are running MPLS at this point depending on where you are.
