Which two components are required to configure an MPLS Layer 3 VPN? (Choose two.)

A unique Route Distinguisher (RD) per customer VRF is essential to differentiate customer routes within the MPLS backbone, even if they overlap. The RD is prepended to the customer's IPv4 or IPv6 prefixes, creating a unique VPNv4 or VPNv6 address family. MP-BGP (Multiprotocol BGP) is used to exchange these VPNv4/v6 routes between the Provider Edge (PE) routers, distributing customer routing information across the MPLS network. LDP is used for label distribution for the MPLS transport, not for customer routes. Pseudowire is for Layer 2 VPNs, not Layer 3. OSPF between PE and CE is a valid option for routing, but not a required component for the MPLS L3VPN itself.
