Referring to the exhibit, a PIM-SM network is set up to enable communication between multicast devices.

Which two statements are true? (Choose two.)

Show Answer
Correct Answer: AB

Before the formation of the rendezvous-point (RP) tree, a join message is sent from R1 to R3, which is the RP, to request to join the multicast group. Additionally, an Internet Group Management Protocol (IGMP) message is sent from the Receiver to R1 to signal its interest in receiving traffic from a particular multicast group. This process ensures that the multicast data can be properly routed from the source to the receivers through the multicast network.

A n B is correct: Before the formation of the rendezvous-point (RP) tree, a join message from a receiver is sent to the RP to request to join a multicast group. This join message contains information such as the group address and the interface on which the receiver is listening for multicast traffic. The IGMP (Internet Group Management Protocol) message is sent by a host on a network to signal its interest in receiving traffic from a particular multicast group. When a receiver wants to join a multicast group, it sends an IGMP message to its local router.
