What is the next step?

A regional MPLS VPN provider operates in two regions and wants to provide MPLS L3VPN service for a customer with two sites in these separate locations. The VPN provider approaches another organization to provide backbone carrier services so that the provider will connect to these two locations.

What is the next step?
A . When edge at different regional sites are connected over the global carrier backbone, MP-eBGP must run between routers to exchange the customer VPNv4 routes.
B . When BGP is used for both route and label exchange, the neighbor a.b.c.d send-label command is used under the address-family VPNv4 command mode.
C . When IGP used for route exchange and LDP for label exchange, MPLS is enabled only on the VRF interface on the backbone-carrier PE side.
D . When eBGP is used for label exchange using the send-label option. MPLS-BGP forwarding is configured under the global ABC CSC PE-to-CE interface.
