A customer is using a service provider to provide a WAN backbone for a 30-site network. In establishing the network, the customer must work within these constraints:
The customer has a self-managed MPLS backbone.
The VPLS WAN backbone of the service provider does not support PIM snooping.
Multicast VPN must be used for multicast support inside some VRFs.
What can the customer do so that multicast traffic is NOT flooded to all sites?
A . Configure static GRE tunnels and run the MPLS and multicast VPN inside these GRE tunnels.
B . Use Label Switched Multicast for the multicast transport.
C . Use PIM-SSM as the multicast routing protocol with IETF Rosen Draft multicast VP
E . Configure a static mapping between multicast addresses and MAC addresses.
F . Use GET VPN to encrypt the multicast packets inside the WA
