Rajesh,

Yes, VPN Service providers' routers need not be connected to the internet to provide VPN services, the VPN service is provided over the service provider backbone with no referral to the internet unless internet access is required in addition to the VPN service.

Hi Rajesh,

The SP routers (Ps and PEs) are connected either via direct links, or via PVCs over ATM backbone for example, all these interfaces must have label switching enabled, all these routers runs IGP, and the PE routers run MBGP with each other to exchange customer VPNv4 routes.
