Relationship among IPv6 PIM protocols
In an IPv6 PIM network, IPv6 PIM-DM cannot work with IPv6 PIM-SM, IPv6 BIDIR-PIM, or IPv6 PIM-SSM.
However, IPv6 PIM-SM, IPv6 BIDIR-PIM, and IPv6 PIM-SSM can work together. When they work together,
which one is chosen for a receiver trying to join a group depends, as shown in
For more information about MLD SSM mapping, see "Configuring MLD."

IPv6 PIM-SM runs for G.
