VTEPs that use headend replication forward unicasts with unknown destination MAC addresses as unicast packets to each VTEP in the same VNI is a correct description of how the VTEPs handle VXLAN traffic forwarding. Headend replication is a method of replicating VXLAN packets at the ingress VTEP instead of using multicast routing. The ingress VTEP sends a copy of the VXLAN packet to each egress VTEP that belongs to the same VNI using unicast tunnels1.
