Which component is used to optimize the multicast distribution tree enabled through the multicast network?

The OMP replicator is a specific component in Cisco SD-WAN responsible for efficiently handling multicast traffic. It centralizes multicast streams and forwards them across the fabric, especially for spokes that cannot directly peer, thereby optimizing the distribution tree and minimizing redundant traffic.

vManage controllers are used for centralized management and orchestration of the SD-WAN network, not for optimizing data plane multicast distribution.

A VPN concentrator provides secure tunnel termination and establishment, but it does not specifically optimize the multicast distribution tree in an SD-WAN context like an OMP replicator.

An IGMP client is an end-device that requests to join a multicast group, rather than a network component designed to optimize the multicast distribution tree itself.
