There are 3 buildings (IT system) that need to be links together but the distance between them are very far apart (min between 230 - 470 km).
How do one manage to provide connection between all of them?
I mean more specifically, is there even a need to personally manage the connection between them or can the service provider handle the MPLS VPN connection?
Consequently, does the router/switch need to have some specific support like MPLS support to handle the MPLS VPN connection or does it need another specific support?
Installing "P2P leased line" in this case will be too expensive due to the limitation in budget (around $45000).
