VXLAN BGP EVPN and OTV Interoperation

A datacenter fabric can be Virtual eXtensible Local Area Network (VXLAN) Border Gateway Protocol
(BGP) Ethernet VPN (EVPN) based, classical ethernet (CE) based, or combined. You can connect different
datacenters over an IP WAN with Layer 2 (such as Overlay Transport Virtualization [OTV]) and Layer 3
technologies, and also connect end hosts between Layer 2 CE and VXLAN pods within a datacenter. With
this feature, you can:
• Configure VXLAN and OTV (with Bridge Domain Interface [BDI]) as a one-box solution. The VXLAN
• Configure OTV with BDI in a datacenter as a one-box solution, instead of a two box solution used in
OTV as the overlay enables Layer 2 connectivity between separate VXLAN BGP EVPN or CE Layer 2
domains while maintaining resiliency and load-balancing benefits of the IP based interconnection.

Prerequisites for VXLAN BGP EVPN and OTV Interoperation

• A Nexus 7000 or 7700 Series switch with an M3 line card.
• Conceptual and configuration knowledge about VXLAN BGP EVPN and OTV datacenter fabrics.
• For a functioning VXLAN BGP EVPN datacenter, configurations should be enabled on the leaf and
and OTV overlays or tunnels are stitched together on a VXLAN BGP EVPN fabric border leaf switch,
ensuring that the Layer 2 traffic between VXLAN and OTV is within the same bridge domain.
