The correct answer is A. diffusion mechanism: Multicast data packets are flooded to all PIM neighbors, and multicast routers generate multicast routing entries; pruning mechanism: If there is no group member under the multicast router, the router sends a pruning forwarding path from the source to the multicast router; assertion mechanism: When there are multiple access networks in the process of multicast forwarding, the router needs to be elected to avoid duplication of multicast packets. See the full explanation below for the reasoning.
Question
Please match the following mechanisms in PIM-DM with their corresponding concepts:
diffusion mechanism, pruning mechanism, assertion mechanism
Multicast data packets are flooded to all PIM neighbors, and multicast routers generate multicast routing entries; If there is no group member under the multicast router, the router sends a pruning forwarding path from the source to the multicast router; When there are multiple access networks in the process of multicast forwarding, the router needs to be elected to avoid duplication of multicast packets
Options
