Architecture

Question

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

Options

AOMP replicator
BvManage controllers
CVPN concentrator
DIGMP client

Explanation

The OMP replicator optimizes multicast distribution trees in a Cisco SD-WAN network by forwarding multicast data plane traffic for devices not directly connected.

Common mistakes.

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