AtubaOS-CX switches are acting as Virtual Extensible LAN (VXLAN) Tunnel Endpoints (VTEPs) WITHOUT Ethernet VPN (EVPN). Does this correctly describe how the VTEPs handle VXLAN traffic forwarding?…
The correct answer is A. Yes. Headend replication is a method of handling BUM traffic in VXLAN networks without EVPN, where the ingress VTEP replicates every BUM packet and sends them as a separate unicast to the remote egress VTEPs in the same VNI. This avoids the need for multicast routing in the underlay…
Question
AtubaOS-CX switches are acting as Virtual Extensible LAN (VXLAN) Tunnel Endpoints (VTEPs) WITHOUT Ethernet VPN (EVPN). Does this correctly describe how the VTEPs handle VXLAN traffic forwarding? Solution: VTEPs that use headend replication forward broadcasts as unicast packets to each VTEP in the same VNI.

Explanation
Headend replication is a method of handling BUM traffic in VXLAN networks without EVPN, where the ingress VTEP replicates every BUM packet and sends them as a separate unicast to the remote egress VTEPs in the same VNI. This avoids the need for multicast routing in the underlay network, but it can increase the load on the ingress VTEP. Therefore, this correctly describes how the VTEPs handle VXLAN traffic forwarding without EVPN.
