Refer to the exhibit. All PE routers are configured with full-mesh MP-BGP and VPNv4 routing to provide L3VPN services. A central service VRF is implemented, to provide- management and monitoring products to customers with dedicated VRFs .The objective of this design to provide routing between the central services VRF and VRFs A and B. Which implementation achieves this goal?
