1.  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.

   engine failover for redundancy test.

   Objective:

  Send <X> frames to DUT with different SA and DA from CE using
  the traffic generator. Send <X> frames from traffic generator to
  R1 with different SA and DA so that <2X> MAC address will be learned
  in DUT. There is a bi directional traffic flow with <X>  pps in each
  direction. Then do a routing engine failover.


Procedure:


Configure PBB-EVPN EVI in R1,MHPE2,DUT. All 4 routers except CE are
running MPLS,BGP,RR is acting as route reflector to R1,MHPE2 and
DUT. Once the BGP is established. Record the DUT PBB-EVPN table. For
MH PE ESI must be configured per IFD/Interface. Using RT(traffic
generator) send the traffic to the routers.

Measurement:

There should be 0 packet loss which is the ideal case, No change
in the DF role. There should not be any withdraw of routes from DUT.

   configured.

ip/ipv6 address to the same target gateway ip address. Measure whether
<X> MAC+IPv4 address/MAC+IPv6 address of the hosts are learned in DUT.


 Procedure:

 Configure EPN EVI in R1,MHPE2,DUT.All 4 routers except CE are
 running MPLS,BGP,RR is acting as route reflector to R1,MHPE2 and
 DUT. Once the BGP is established. Record the DUT EVPN table. For MH PE
 ESI must be configured per IFD/Interface. Using RT(traffic
 generator) send arp/ICMPv6 request to the DUT which has gateway
  configured.

  Measurement:

  The DUT must learn <X> MAC+IPV4/MAC+IPv6 and it must advertise the X
   MAC+IPV4/MAC+IPV6 to the remote router.
