Abstract
Techniques for extending unicast to multicast service reflection to SD-WAN overlay networks using a virtual interface (VIF) through a centralized policy are described herein. The techniques may include receiving, by a network controller of a SD-WAN, a centralized data policy for unicast to multicast service reflection, transmitting, by the network controller and to a network edge device, the centralized data policy, designating, by the network edge device, a primary replicator to act as a multicast source and replicate packets toward a last hop router (LHR), configuring, on the primary replicator, a VIF usable to translate unicast packets to multicast packets, and applying, by the primary replicator, the centralized data policy on received packets.
