What two requirements must be in place to deploy L3VPN over an MPLS network?

For L3VPN over MPLS, PE (Provider Edge) routers need to exchange VPN routing information, which is achieved using Multiprotocol iBGP (MP-iBGP) between them. This allows the PEs to distribute VPNv4 routes, including VPN labels, across the MPLS backbone. The P (Provider) and PE routers must also have a label distribution protocol enabled, such as LDP (Label Distribution Protocol) or RSVP-TE (Resource Reservation Protocol - Traffic Engineering), to establish label-switched paths (LSPs) across the core network. These LSPs are essential for forwarding labeled VPN traffic between PE routers. Incorrect options: The P routers do not require RSVP specifically; LDP is more commonly used for label distribution in the core. PE routers use MP-BGP to exchange VPN routes with other PEs, not typically MP-eBGP to connect to CEs (Customer Edge) routers. PE-CE routing can be eBGP, iBGP, or IGP, but not MP-eBGP for VPN route exchange. P routers do not need MP-iBGP toward PE routers; their role is label switching based on LDP/RSVP, not VPN route exchange.
