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. VXLAN is a tunneling protocol that encapsulates layer 2 traffic over an IP network using VXLAN Network Identifiers (VNIs) to identify different layer 2 segments. VXLAN Tunnel Endpoints (VTEPs) are devices that perform the encapsulation and decapsulation of VXLAN packets. VTEPs…
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 broadcast as multicast to each VTEP in the same VNI.

Explanation
VXLAN is a tunneling protocol that encapsulates layer 2 traffic over an IP network using VXLAN Network Identifiers (VNIs) to identify different layer 2 segments. VXLAN Tunnel Endpoints (VTEPs) are devices that perform the encapsulation and decapsulation of VXLAN packets. VTEPs can use different methods to handle broadcast, unknown unicast, and multicast (BUM) traffic within a VNI. One of these methods is headend replication, which means that the VTEP that receives a BUM packet replicates it and sends it as a unicast to each remote VTEP in the same VNI. This method does not require 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.
