You are the lead IP/MPLS network designer of a service provider called XYZ.
You are leading a design discussion regarding IPv6 implementation in the XYZ MPLS network, using MPLS 6PE/6VPE techniques.
Currently, XYZ provides IPv4 multicast services over an MPLS network by using MVPN, and would like to provide parallel IPv6 multicast services.
Which three multicast solutions should be enabled? (Choose three.)

To provide IPv6 multicast services over an MPLS network using MPLS 6PE/6VPE techniques, the following multicast solutions should be enabled:
B. MPLS 6PE/6VPE: This solution provides IPv6 multicast support by default in an MPLS network. 6PE (IPv6 Provider Edge) and 6VPE (IPv6 VPN Provider Edge) are techniques used for transporting IPv6 packets over an MPLS core network. These techniques allow the separation of IPv6 forwarding from IPv4 forwarding, thereby allowing independent control of IPv6 routing and forwarding.
D. PIM-DM: Protocol-Independent Multicast Dense Mode (PIM-DM) can be used to enable IPv6 multicast in conjunction with MPLS 6PE/6VPE. PIM-DM is a multicast routing protocol that supports dense mode multicast traffic. When used in conjunction with MPLS 6PE/6VPE, it enables the forwarding of IPv6 multicast traffic across the MPLS network.
E. M VPN for IPv6 multicast service: Multicast VPN (M VPN) can be used to provide IPv6 multicast services over an MPLS network. M VPN is an extension to the MPLS VPN technology that supports the forwarding of multicast traffic across the MPLS network. It uses techniques such as GRE and PIM to transport multicast traffic across the MPLS network.
Option A, native IPv6, only for multicast services, is not a viable solution. Native IPv6 only supports unicast traffic and does not support multicast traffic.
Option C, an overlay model using Layer 2 MPLS tunnels, is not a suitable solution as it does not provide native IPv6 multicast support and can introduce additional overhead and complexity to the network design.
