Question ID 18588	Which statement is true about IGMP?
Option A	Multicast sources send IGMP messages to their first-hop router, which then generates a PIM join message that is then sent to the RP.
Option B	Multicast receivers send IGMP messages to their first-hop router, which then forwards the IGMP messages to the RP.
Option C	IGMP messages are encapsulated in PIM register messages and sent to the RP.
Option D	Multicast receivers send IGMP messages to signal their interest to receive traffic for specific multicast groups.
Option F	Answer : D Explanation: In the example shown above, the receivers (the designated multicast group) are interested in receiving the video data stream from the source. The receivers indicate their interest by sending an Internet Group Management Protocol (IGMP) host report to the routers in the network. The routers are then responsible for delivering the data from the source to the receivers. Reference: http://www.cisco.com/c/en/us/td/docs/ios/solutions_docs/ip_multicast/White_papers/mcst_o vr.html
