Why each option
PIMv6 supports Sparse Mode, Source Specific Multicast, and Embedded RP for efficient and scalable multicast routing in IPv6 networks.
Embedded RP is an IPv6-specific PIM feature that allows the Rendezvous Point address to be encoded directly into the IPv6 multicast group address, simplifying RP discovery.
MSDP (Multicast Source Discovery Protocol) is an IPv4-specific protocol used to connect multiple PIM-SM domains and is not supported in PIMv6.
Auto-RP is a Cisco proprietary IPv4-specific mechanism for dynamic RP discovery and is not supported in PIMv6.
PIM Sparse Mode (PIM-SM) is a fundamental PIM operational mode widely supported in PIMv6, which uses a Rendezvous Point to build shared multicast distribution trees.
Source Specific Multicast (SSM) is a PIM mode that allows receivers to explicitly specify the source of a multicast stream and is fully supported in PIMv6.
PIM Dense Mode (PIM-DM) is an older, flood-and-prune approach to multicast that is generally considered obsolete and is not supported in PIMv6.
