1. Introduction
EVPN is defined in RFC 7432, and describes BGP MPLS- based Ethernet
VPNs (EVPN). PBB-EVPN is defined in RFC 7623, discusses how Ethernet
Provider backbone Bridging can be combined with EVPNs to provide a
new/combined solution. This draft defines methodologies that can be
used to benchmark both RFC 7432 and RFC 7623 solutions. Further,
this draft provides methodologies for benchmarking the performance of
EVPN data and control planes, MAC learning, MAC flushing, MAC ageing,
convergence, high availability, and scale.

must relearn all type 1,2,3 and 4 from remote routers. The DUT must
be subjected to various values of N to find the optimal scale limit
6.2. PBB-EVPN To measure the scale limit with trigger.
Objective:
To measure the scale limit of DUT for PBB-EVPN.
Topology : Topology 3
Procedure:
The DUT,MHPE2 and SHPE3 are scaled to "N" PBB-EVPN instances. Clear
BGP neighbors in the DUT Once adjacency is established in DUT, check
routes received from SHPE3 and MHPE2.

Measurement :
There should not be any loss of route types 2,3 and 4 in DUT. The
DUT must relearn all type 2,3 and 4 routes from remote routers. The
DUT must be subjected to various values of N to find the optimal
scale limit.
6.3. To measure the convergence time of DUT with scale and traffic.
Objective:
To measure the convergence time of DUT when the DUT is scaled with
EVPN instance along with traffic.
Topology : Topology 3
Procedure:
Scale N EVIs in DUT,SHPE3 and MHPE2.Send F frames to DUT from CE
using traffic generator with X different SA and DA for N EVI's. Send
F frames from traffic generator to SHPE3 with X different SA and DA.
There will be 2X number of MAC address will be learned in DUT EVPN
MAC table. There is a bi directional traffic flow with F pps in each
direction. Then clear the BGP neighbors in the DUT. Once the
adjacency is restored in DUT. Measure the time taken to learn 2X MAC
address in DUT MAC table.
Measurement :
The DUT must learn 2X MAC address. Measure the time taken to learn
2X MAC in DUT. Repeat these test and plot the data.The test is
repeated for "N" times and the values are collected.The convergence
time is calculated by averaging the values obtained by "N" samples.
Convergence time in sec = (T1+T2+..Tn/N)

Scale N PBB-EVI's in DUT,SHPE3 and MHPE2.Send F frames to DUT from CE
using traffic generator with X different SA and DA for N EVI's. Send
F frames from traffic generator to SHPE3 with X different SA and DA.
There will be 2X number of MAC address will be learned in DUT PBB-
EVPN MAC table. There is a bi directional traffic flow with F pps in
each direction. Then clear the BGP neighbors in the DUT. Once the
adjacency is restored in DUT. Measure the time taken to learn 2X MAC
address in DUT PBB-MAC table.
Measurement :
The DUT must learn 2X MAC address. Measure the time taken to learn
2X MAC in DUT. Repeat these test and plot the data. The test is
repeated for "N" times and the values are collected. The convergence
time is calculated by averaging the values obtained by "N" samples.
Convergence time in sec = (T1+T2+..Tn/N)
7. SOAK Test
This is measuring the performance of DUT running with scaled
configuration with traffic over a peroid of time "T'". In each
interval "t1" the parameters measured are CPU usage, memory usage,
crashes.
7.1. To Measure the stability of the DUT with scale and traffic.
Objective:
To measure the stability of the DUT in a scaled environment with
traffic.
Topology : Topology 3
Procedure:
Scale N EVI's in DUT,SHPE3 and MHPE2.Send F frames to DUT from CE
using traffic generator with different X SA and DA for N EVI's. Send
F frames from traffic generator to SHPE3 with X different SA and DA.
There will be 2X number of MAC address will be learned in DUT EVPN
MAC table. There is a bi directional traffic flow with F pps in each
direction. The DUT must run with traffic for 24 hours, every hour
check for memory leak, crash.
Measurement :

Take the hourly reading of CPU, process memory. There should not be
any leak, crashes, CPU spikes.
7.2. PBB-EVPN to measure the stability of DUT with scale and traffic.
Objective:
To measure the stability of the DUT in a scaled environment with
traffic.
Topology : Topology 3
Procedure:

There will be 2X number of MAC address will be learned in DUT PBB-
EVPN MAC table. There is a bi directional traffic flow with F pps in
Each direction. The DUT must run with traffic for 24 hours, every
hour check the memory leak, crashes.
Measurement :
Take the hourly reading of CPU process, memory usages. There should
not be any memory leak, crashes,CPU spikes.
