What is EVPN-VXLAN?
EVPN-VXLAN is a network fabric that extends layer 2 connectivity as a network overlay over an existing physical network. It is an open standards technology that creates more agile, secure, and scalable networks in campuses and data centers.
EVPN-VXLAN Explained
EVPN-VXLAN is an open standards technology that solves the limitations of traditional VLAN-based networks by creating a network fabric that extends layer 2 connectivity as a network overlay over an existing physical network. EVPN-VXLAN consists of:
- Ethernet VPN (EVPN) which is used as the overlay control plane and provides virtual connectivity between different layer 2/3 domains over an IP or MPLS network.
- Virtual extensible LANs (VXLAN), a common network virtualization overlay protocol that expands the layer 2 network address space from 4,000 to 16 million.
