Then clear bgp neighbor.There should not be any loss of routes or any crashes. Send F frames from CE to DUT from traffic generator with different SA and DA for N EVI's. Send F frames from traffic generator to R1 with different SA and DA for N EVI's.so that 2F number of mac address will be learned in DUT. There is a bi directional traffic flow with F pps in each direction. Then clear the bgp nei in DUT after the bgp comes up and started learning the routes, measure the time taken to learn all 2F mac routes. Procedure: Configure 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 comes up check the DUT evpn table.For MH PE ESI must be configured per IFD/Interface. Using RT(traffic generator) to send the traffic to the routers. Measurement: The DUT must learn all 2F mac address.Measure the time taken to learn 2F mac in DUT, measure the flood traffic time "t" of DUT PBB-EVPN To Scale the DUT to "N" PBB-EVPN instances and clear bgp in DUT with traffic.Measure the convergence time Objective: The main purpose of the test the DUT performance to scale N pbb- evpn instances with traffic.Then clear bgp neighbor.There should not be any loss of routes or any crashes.Send F frames from CE to DUT from traffic generator with different SA and DA for N pbb-evpn instances.Send F frames from traffic generator to R1 with different SA and DA for N pbb-evpn instances.so that F mac address will be learned in DUT.There is a bi directional traffic flow with F pps in each direction.Then clear the bgp nei in DUT after the bgp comes up and started learning the routes, measure the time taken to learn all 2F macs in DUT.
