Usage and Applicability of BGP MPLS-Based Ethernet VPN
Abstract
This document discusses the usage and applicability of BGP MPLS-based
Ethernet VPN (EVPN) in a simple and fairly common deployment
scenario. The different EVPN procedures are explained in the example
scenario along with the benefits and trade-offs of each option. This
document is intended to provide a simplified guide for the deployment
of EVPN networks.
