Which multicast component is irrelevant when defining a multicast replicator outside the local network without any multicast sources or receivers? Reveal answer details Close answer detailsCorrect answerB Explanation When defining a multicast replicator outside the local network without any multicast sources or receivers, the PIM interfaces (B) are irrelevant. PIM (Protocol Independent Multicast) interfaces are used to establish multicast routing within a network, specifically for managing multicast traffic within the local network. In the absence of multicast sources and receivers within the local network, PIM interfaces serve no purpose, as there is no multicast traffic to route or manage. The focus in this scenario would be on the configuration of multicast replication and routing outside the local network, as indicated by the mention of defining a multicast replicator.
