Introduction EVPN is defined in RFC7432 which describes procedures for BGP MPLS-based Ethernet VPNs(EVPN).This document defines the methodologies for benchmarking performance of EVPN. The scope of this document is to provide methodologies for benchmarking EVPN data, control plane MAC learning, MAC flush ,MAC aging, convergence, high availability, scale. The methodologies defined for EVPN can be used for benchmarking the performance of PBB-EVPN.PBB-EVPN is defined in RFC 7623.It is being deployed in provider network. The difference between PBB-EVPN and EVPN is the former learns the customer MAC in data plane the later learns in control plane.
