EVPN VXLAN Design Guide   A Detailed Overview of the EVPN & VxLAN Protocols, Route Types, Use-Cases and Architectures   1. Introduction This document describes the operation and configuration of BGP EVPN Services over a VXLAN (Virtual eXtensible LAN) overlay on Arista platforms. The focus in this design guide is VxLAN as the protocol for the data-plane encapsulation for the overlay tunnels, and the functionality of the Multiprotocol BGP (MP-BGP) EVPN address-family for control plane signaling in the overlay.  MP-BGP EVPN is not only used for advertising MAC addresses, MAC and IP bindings and IP prefixes across the overlay; it...

Arista Layer 2 VTEP EVPN Route Type-1 Support   Arista Layer 2 EVPN VTEP Inter-Operation With A/A Multi-homed Third-Party Layer 3 EVPN VXLAN VTEPs     Introduction   This document will explain the configurations required to support inter-working with EVPN VXLAN A/A multi-homed VTEPs, also known as L2 ECMP in VxLAN EVPN.   Currently, EOS uses MLAG is used to achieve Multi-homing in EVPN VxLAN Topologies, with an any-cast VxLAN VTEP configured on the MLAG pair, and as such does not need to support EVPN Multihoming Tx (Type-1 route generation). EOS can however install received Type-1 routes and can...

Introduction This document describes the operation and configuration of BGP EVPN with a VXLAN forwarding plane, for the construction of multi-tenant Layer 2 networks, termed L2VPNs within this document, over a layer 3 leaf-spine network. The configuration and guidance within the document unless specifically noted are based on the platforms and EOS releases noted in the table below Platform Software Release 7050X Series EOS release 4.18.1 7050X2 series EOS release 4.18.1 7060X Series EOS release 4.18.1 7160 series EOS release 4.18.1 7280R/7500R EOS release 4.18.1   Leaf spine underlay architecture EVPN with a VXLAN forwarding plane provides the ability to...
