A customer CE device advertises its routes to the service provider. Which of the following responsibilities belongs to the PE, not the CE?

The PE (Provider Edge) router is responsible for originating VPNv4 routes into MP-BGP. It takes the customer's IPv4 prefixes, adds a Route Distinguisher (RD) to make them globally unique, and assigns Route Targets (RTs) to control their distribution within the MPLS VPN cloud. The CE (Customer Edge) router is unaware of VPNv4 or MP-BGP; it simply advertises standard IPv4 routes. Assigning RDs to customer prefixes is a PE function, not a CE function. The provider's IGP runs in the global routing table, not typically within a customer's VRF by default, and the PE handles the interaction between the customer's routing and the provider's network. MPLS is a provider technology and is terminated on the PE, not directly on the CE.
