1 Introduction
EVPN which is defined in RFC7432 which describes procedures for
BGP MPLS-based Ethernet VPNs(EVPN).This document defines the
methodologies for benchmarking performance of EVPN.EVPN has been
implemented with many varying designs in order to achieve their
intended network functionality.The scope of this document is to
provide methodologies for benchmarking evpn data,control plane mac
learning,mac flush,mac ageing,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.
1.1 Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL"
in this document are to be interpreted as described in RFC 2119
[RFC2119].

4. Test Procedure
The test defined to bench mark the performance of EVPN mac learning
in control pland and data plane. Mac flush,High Availability,
convergence time in link failures,scale scenarios.
4.1 MAC Learning in Control plane and Data Plane
The MAC will be learned in data plane and control plane, test is to
measure the time taken to learn the "X" number of mac's in time "T"
sec. The data plane learning will from the locally connected
interface. The control plane learning is through BGP advertisements
from the remote PE. Let the local learning time be "T" and control
plane learning time be "T'". The data plane mac learning can be
measured using the parameters defined in RFC 2889 section 5.8.
4.2 MAC flush for locally learned and remote learned MAC
The time taken to flush the "X" locally learned mac, let it be "T1"
sec, once the traffic is stopped. The time taken to flush the remote
mac which is learned by control plane let it be "X" macs.The time
taken to flush the "X" remote macs, which is measured as "T2" sec.
4.3 High Availability
The traffic is flowing bi direction. The bgp is converged,consider
there are "X" numbers of macs learned locally and remotely.
Then traffic is flowing at "P" packets per sec. The traffic generator
is measuring the Tx and Rx packets, while the routing engine fail over there
should not any packet loss the router tester must show both "P"
packet per seconds.
4.4 Convergence Time
During any events like link failure, hard reset measure the time
taken to learn "X" mac's locally and remotely.
4.5 Scale
This is to measure the performance of DUT in scaling to "X" EVPN
instances. The measured parameters are CPU usage, memory
leak,crashes.

This test is used to measure the performance of DUT over a period of
time,with scaled configuration and traffic over a period of time
"T'". In each interval "t1" the parameters measured are CPU usage,
memory usage and crashes.
