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 Figure 100.

or more information about MLD SSM mapping, see "Configuring MLD."

Configuring IPv6 PIM-DM

This section describes how to configure IPv6 PIM-DM.

IPv6 PIM-DM configuration task list

A receiver joins IPv6 multicast group G.

G is in the IPv6

SSM group range?

IPv6 BIDIR-PIM runs for G.

IPv6 BIDIR-PIM is enabled?

G has an IPv6 BIDIR-PIM

RP?

Yes

IPv6 PIM-SSM runs for G.

An MLD-SSM mapping is

configured for G?

IPv6 PIM-SM runs for G.

An IPv6 multicast source is

specified?

Yes
