ACME Corporation is integrating IPv6 into their network, which relies heavily on multicast distribution of data. Which two IPv6 integration technologies support IPv6 multicast? (Choose two.)

6VPE transports IPv6 over an MPLS VPN core using label switching for unicast prefixes and does not provide a mechanism to forward IPv6 multicast traffic.

6PE uses MPLS label imposition to carry IPv6 unicast routes across an MPLS backbone and has no support for IPv6 multicast forwarding.

Dual stack runs native IPv6 directly on the network stack alongside IPv4, inheriting full IPv6 feature support including multicast without any encapsulation or translation. Because packets are native IPv6, multicast group membership and forwarding work exactly as in a pure IPv6 environment.

ISATAP is explicitly designed for unicast IPv6-over-IPv4 tunneling within a site and lacks any multicast support by specification.

6to4 automatic tunneling embeds an IPv4 address in an IPv6 prefix for unicast connectivity only and cannot carry IPv6 multicast traffic.

IPv6-in-IP (protocol 41 manual tunnels) encapsulates IPv6 packets within IPv4, and unlike automatic tunnel mechanisms such as 6to4 or ISATAP, manual IPv6-in-IP tunnels can be configured to carry IPv6 multicast traffic across an IPv4 infrastructure.
