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

Figure 10. IxScriptMate L3 VPN RSVP-TE egress performance.IxExplorer LDP Extended Martini Session ScalabilityTestObjective: To determine the maximum number of LDP Extended Martini sessions the DUTcan sustain at one time.Test setup: One Ixia port connected to the DUT (see Figure 11).Methodology:1. An OSPF session is established with the DUT.2. An LDP basic session is established with the DUT, advertising the Ixia port loopbackaddress as a FEC.3. A number of LDP Extended Martini sessions (based on test expectations) areestablished with the DUT with one or more Layer 2 VC FECs advertised per session.4. Status on the port is monitored to determine if all configured sessions aresuccessfully established. Figure 14 shows the MPLS Martini labels learned byIxExplorer from the DUT — one for each session.5. If all sessions are successfully established, the number of extended sessionsconfigured is increased and the test rerun. If not all are established, the number ofsessions is lowered and the test repeated.Results: LDP Extended Martini session capacity.25
