4. VPN Merging Test ObjectiveThis test determines a PE’s ability toimport different VPNs to a single VPN byrunning traffic flows <strong>and</strong> verifying receivedstatistics for each VRF instance.SetupThis test requires at least two tester ports.Tester port 1 acts as a CE for trafficgeneration to all VPN routes learned whiletester port 2 emulates a group of PErouters, each from a different VRF/VPNadvertising unique prefixes. The DUT PEreceives all routes <strong>and</strong> merges them intoone common VPN to distribute to testerport 1.AS 500VRFs are being imported<strong>and</strong> traffic verifiedby each PE receiving statsemulation porttest port 2PE1IXIAtraffic flowsVRF1VRF2IXIADUTPE2VRF3importVRF1, VRF2VRF3, VRF4VRF5, VRF6IXIAPE3VRF4VRF5external VRFsadvertising to the DUTIXIAtraffic flowsVRF6Figure 11.
