Refer to the exhibit. A network engineer applies a configuration to multiple PE routers participating in an MLDP. Each PE creates the same VRF to support a single customer, which has officers located in several different regions. The PEs provide connectivity for hosts that use multicast services across a VPN. After the configuration is applied and the PEs are brought up, which additional action must the engineer take to enable multicast in the network?

• A.Set a common VPN ID on each participating PE.
• B.Enable PE routers to send labels for multicast traffic only.
• C.Implement PIM-DM on all P routers within the service provider core.
• D.Implement bidirectional PIM on all PE routers within the service provider core.
