Question
How do receivers request to join multicast streams in a Cisco SD-WAN network?
Options
- AMulticast service routes with the vSmart controller.
- BIGMP membership reports directly with a multicast router.
- CPIM messages with the nearest neighboring multicast router.
- DIGMP membership reports directly with the vBond orchestrator.
Explanation
This question asks about the mechanism receivers use to join multicast streams within a Cisco SD-WAN network.
Common mistakes.
- A. Multicast service routes are part of how the vSmart controller learns about multicast sources and group ranges in the overlay, not how receivers request to join.
- C. PIM messages are used by routers to build and maintain multicast distribution trees, not directly by receivers to request membership. Receivers use IGMP.
- D. The vBond orchestrator's primary role is orchestration and initial authentication for SD-WAN devices, not handling real-time multicast membership reports from end receivers.
Concept tested. Multicast receiver signaling (IGMP)
