When receiving a VPNv4 route from a CE (CE 1 or CE 2 in this example), a service provider PE

replaces the RD of the VPNv4 route with the RD of the MPLS VPN on the service provider network

where the CE resides, adds the export target attribute of the MPLS VPN on the service provider

network to the extended community attribute list, and then forwards the VPNv4 route as usual.

To implement exchange of sub-VPN routes between customer PEs and service provider PEs,

MP-EBGP peers should be established between service provider PEs and customer CEs.
