An engineer is implementing IGMP with SSM on a multicampus network that supports video streaming. Which task must the engineer perform as part of the process?

Source-Specific Multicast (SSM) explicitly requires IGMPv3 because only this version of IGMP allows receivers to express interest in receiving multicast traffic from a specific source to a specific group using (S,G) join messages, unlike older IGMP versions.

Bidirectional PIM is a PIM mode designed for many-to-many applications where source location is unknown, and it does not directly align with or is required by SSM, which typically works with PIM-SM (Source-Specific Mode).

SSM does not require a Rendezvous Point (RP) because receivers explicitly specify the source in their join messages, allowing PIM to build source-specific trees directly without RP assistance.

The PIM bsr-candidate command is used for dynamic RP discovery in PIM-SM, which is not relevant to SSM since SSM operates without the need for an RP.
