2. Route ReflectorPE Scalability TestObjectiveConfirm the number of configured PEs thata DUT can peer with and maintain theability to reflect routes.SetupThe test requires two tester ports — one totransmit traffic and one to receive. Thetransmit direction of traffic isunidirectional. Test port 2 is used toadvertise the PE route-reflector clients,while test port 1 sends traffic to verify theadvertised prefixes (Figure 4). During thetest, tester port 2 increases the number ofadvertised PEs each with new NLRI. Ixia’snew L3 VPN wizard utility in softwarerelease IxOS 3.80 can accomplish thissetup with minimal configuration steps.Routes can be verified with flows of trafficstreams from Ixia’s automated trafficgenerator utility.PE1routereflectorclientsIXIAprefix_1connect toroute reflectorclienttraffic reflected back to PEsPEroute reflectorrDUTconnect n toroute reflector e clientPE2PE3traffic flows to all other prefixesPE4IXIAIXIAIXIAprefix_2prefix_3prefix_4emulated PEssingle portIXIAPE0number of PEsincreases per iterationPE5IXIAprefix_5Figure 4.
