What is L2VPN EVPN?

EVPN is a next-generation full-service bearer VPN solution. It subverts the traditional L2VPN’s mechanism of learning MAC addresses on the forwarding plane, introduces the control plane, and uses BGP extensions to transmit MAC address information.

How do I set up an EVPN?

Configuring EVPN with VLAN-Based Service

  1. Configure the first routing instance of type evpn named evpn1 .
  2. Configure the access interface for handling EVPN traffic.
  3. Configure a Layer 3 integrated and routing (IRB) interface for the evpn1 routing instance.

What is EVPN Cisco?

Ethernet VPN (EVPN) and Provider Backbone Bridging-EVPN: Next Generation Solutions for MPLS-based Ethernet Services – Cisco.

What is EVPN and VXLAN?

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.

What is VXLAN EVPN?

EVPN-VXLAN refers to 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.

Is EVPN a VXLAN?

EVPN is a control plane for VXLAN that is used to reduce flooding in the network and resolve scalability concerns. EVPN uses multiprotocol BGP (MP-BGP) to exchange information between VXLAN tunnel endpoints (VTEPs). EVPN was introduced in RFC 7432, and RFC 8365 describes VXLAN-based EVPN.

Why do we need EVPN for VXLAN?

Benefits of EVPN-VXLAN Programmability allows you to easily automate. Its open standards-based architecture ensures backwards and forwards interoperability. Integrated and efficient Layer 2 and Layer 3 connectivity with control plane-based learning. Easy network scalability that’s based on business needs.
