JN0-683 · Question #61
What are two ways in which an EVPN-signaled VXLAN is different from a multicast-signaled VXLAN? (Choose two.)
The correct answer is B. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using BGP. C. An EVPN-signaled VXLAN is less resource intensive. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using BGP EVPN uses BGP control plane to advertise MAC-to-VTEP mappings and perform VTEP autodiscovery, removing the need for multicast in the underlay. An EVPN-signaled VXLAN is less resource intensive Unlike multicast…

Explanation
An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using BGP EVPN uses BGP control plane to advertise MAC-to-VTEP mappings and perform VTEP autodiscovery, removing the need for multicast in the underlay. An EVPN-signaled VXLAN is less resource intensive Unlike multicast VXLAN, EVPN doesn't rely on flooding unknown traffic via multicast groups in the underlay, reducing bandwidth and CPU usage.
