What is a reason for implementing MPLS in a network？（）

• A、MPLS eliminates the need of an IGP in the core.
• B、MPLS reduces the required number of BGP-enabled devices in the core.
• C、Reduces routing table lookup since only the MPLS core routers perform routing table lookups.
• D、MPLS eliminates the need for fully meshed connections between BGP enabled devices.
