Explanation

EVPN enables fast convergence and updates: EVPN (Ethernet VPN) provides a more scalable and efficient control plane for VXLAN, enabling fast convergence and quicker updates for network changes. This is achieved through the use of BGP (Border Gateway Protocol) as the control plane protocol, which allows for efficient distribution of MAC and IP address information. Both multicast and EVPN can facilitate MAC learning: Both multicast and EVPN can handle MAC address learning in a VXLAN environment. In multicast-based VXLAN, MAC addresses are learned and distributed via multicast control messages, whereas in EVPN, MAC addresses are distributed via BGP advertisements, which are more efficient and scalable. Multicast does not require as many resources: Multicast-based VXLAN control planes use standard multicast protocols like PIM (Protocol Independent Multicast) to forward traffic across the VXLAN fabric. While multicast has resource requirements for managing multicast groups, it does not require the same level of control-plane processing as EVPN, which uses BGP to handle MAC address advertisements. However, multicast can be less agile and may require additional
