    In MPLS terminology, Router in Customer end is called CE and in ISP is PE(Provider Edge).Connectivity from CE to PE can be through different modes, wimax, wired or through Mux. In case of MPLS VPN, once the packet towards a destination from CE hits PE. It checks the route in VRF. It would be learned via MPBGP from different PE or same PE. If it is learned via different PE. Router will check how to reach the Next hop, this would via an IGP(OSPF or ISIS). Now MPLS starts. Router will check for the lable assigned towards the destination , then forwards to P routers. P router swaps the labels and finally reach the other PE, then the traffice is forwarded to CE.Interconnecting PE to P would be mainly through TXN Fiber optic media with the help of MUX.
