4. VPN Merging Test ObjectiveThis test determines a PE’s ability toimport different VPNs to a single VPN byrunning traffic flows and 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 and merges them intoone common VPN to distribute to testerport 1.AS 500VRFs are being importedand traffic verifiedby each PE receiving statsemulation porttest port 2PE1IXIAtraffic flowsVRF1VRF2IXIADUTPE2VRF3importVRF1, VRF2VRF3, VRF4VRF5, VRF6IXIAPE3VRF4VRF5external VRFsadvertising to the DUTIXIAtraffic flowsVRF6Figure 11.

Methodology1. Tester port 1 advertises a CE devicesending traffic to severaldestinations from the merged VPN.2. Tester port 2 advertises a configurednumber of PEs, each with a givenamount of VRF sites. These siteprefixes should be confirmed in theDUT’s forwarding table for each VRFinstance.3. The VRF instances are merged toone common VPN. This VPN is on thetester port 1 VRF, where traffic isbeing sent to each destination.Figure 12 shows Ixia VPN wizardconfiguration for VRF setup section.Each parameter is configured in thewizard setup pertaining to P, PE, andVRF specifics.4. Start traffic flows from the tester port1 port and confirm the delivery of theflows on a per PE or VRF basis.Figure 12.
