Multi-Protocol Label Switching (MPLS) Conformance and ... - Ixia

Appendix: MPLS Testing ExamplesThis appendix contains several examples of brief MPLS test plans, with specific examplesshowing how Ixia’s solutions address the challenges of MPLS testing.IxANVL LDP Conformance TestObjective: To characterize the MPLS router’s compliance with LDP RFC standards.Test setup: IxANVL Linux workstation connected directly, or via Ixia test hardware, to DUTwith two network connections — one for request packets and one for response packets.Methodology: IxANVL runs a number of test cases against the DUT based on directinterpretation of the LDP RFCs 3036 and 3215.1. Configure each IxANVL network interface with the appropriate network parameters,including those of the DUT such as IP address, MAC address, gateway, etc.2. Specify configuration of the DUT, typically via command scripts such as Expectscripts.3. Select the set of IxANVL LDP test cases to run during the test session (see Figure 7).4. Run IxANVL in batch mode with the command scripts, reconfiguring the DUT asrequired between test cases to match the IxANVL test setup.Results: Number of tests passed/failed, including reasons for failed cases (see Figure 8).Figure 7.
