Figure 9. IxScriptmate ingress/egress forwarding performance test configuration.Methodology1. The port simulating the PE/P routerestablishes an IGP session with theDUT <strong>and</strong> advertises the loopbackaddress of the simulated PE router.Traffic engineering parameters areadvertised using OSPF-TE, IS-IS-TE,or LDP protocols.2. Bi-directional LSPs are establishedusing RSVP-TE or LDP.3. A multi-protocol internal <strong>BGP</strong> (MPi<strong>BGP</strong>)session is established with theDUT.4. The port simulating the PE routertransmits MPLS traffic at thespecified rate; if frame loss occurs,the transmission rate is alternatelyreduced/increased using a binarysearch algorithm to determine themaximum rate at which the DUT canforward traffic without loss.12 Copyright © Ixia, 2004 <strong>BGP</strong>/<strong>L3VPN</strong> <strong>Conformance</strong> <strong>and</strong> <strong>Performance</strong> Testing: Sample Test Plans
