EVPN

EVPN (Ethernet Virtual Private Network) is a standards-based control plane technology that provides advanced Layer 2 and Layer 3 VPN services over IP/MPLS and IP-only networks, commonly used with VXLAN overlay networks in modern data center architectures. It enables efficient forwarding, optimal multicast handling, and integrated routing and bridging (IRB) capabilities while supporting advanced features like MAC mobility, ARP suppression, and multi-tenancy. EVPN provides automatic discovery of endpoints, eliminates flooding of unknown unicast traffic, and enables seamless workload mobility across geographically distributed data centers with built-in redundancy and load balancing.
