DATA SHEETAptixia IxNetwork <strong>OSPF</strong> <strong>Emulation</strong><strong>Software</strong><strong>OSPF</strong> <strong>Emulation</strong> <strong>Software</strong><strong>Ixia</strong>’s IxNetwork <strong>OSPF</strong> <strong>Emulation</strong> <strong>Software</strong> is a scalable and flexible solutionfor testing routers or router systems for <strong>OSPF</strong> functionality, capacity, andperformance. Both <strong>OSPF</strong>v2 for IPv4 and <strong>OSPF</strong>v3 for IPv6 networks aresupported. <strong>OSPF</strong> networks can be simulated using either a grid topology or atree-structured topology with configurable tree depth and number of point topoint or broadcast links, thus making it easy to create complicated scenarios.Network ranges can be defined using broadcast or point-to-point link types.With <strong>OSPF</strong>v2, traffic engineering can be enabled on a per-router or a per-linkbasis. Learned LSAs can be displayed on each interface, making it easy toverify the router’s Link State Database (LSDB). In addition, interface statedescriptions can be viewed on a diagnostic port trace to aid in debugging.<strong>Ixia</strong>’s <strong>OSPF</strong> <strong>Emulation</strong> software is extremely scalable. By using multiple testports, large network configurations can be set up with a single <strong>Ixia</strong> chassissystem. By emulating realistic configurations, <strong>Ixia</strong> can perform real-worldstress testing of routers and networks. Multiple <strong>Ixia</strong> routing protocolemulations can be run simultaneously on each port, and wire-speed trafficcan be generated to test the data and control planes.<strong>Emulation</strong> Flexibility<strong>Ixia</strong> provides severalconfiguration modes for <strong>OSPF</strong>emulation testing. The first is therouter paradigm mode whereminimal <strong>OSPF</strong> knowledge isrequired. Routers, interfaces,and routes are created based onIP addresses, Network Masks,Network Type, Area ID, RouteOrigins, and Tree or grid likenetwork topology. Thisinformation is then used toconstruct and flood theappropriate Link StateAdvertisements (LSAs) in therespective adjacencies. Eachemulated router is capable ofadvertising thousands of intraareaand external type routes.The second mode, user LSAs,allows users to directly configureLSAs. Tips, pull-downs, andcheckboxes are used to facilitatedata entry. LSAs can originatefrom one user defined LSAgroup or be segmented basedon routers, areas, or testscenarios. Tcl scripts can alsobe used to quickly generatethousands of user-defined LSApackets.The third mode, RAW streamencapsulation mode, providesusers with extreme flexibility inconstructing and manipulating<strong>OSPF</strong> messages for conductingnegative testing.26601 Agoura Road | Calabasas, CA 91302 USA | Tel + 1-818-871-1800 | | www.ixiacom.comDocument No.: 915-1809-01 Rev B November 2013 - Page 1

DATAScalabilityThousands of <strong>OSPF</strong> sessions and millions of routes can besupported on a single <strong>Ixia</strong> chassis with CPU per port LoadModules. Each <strong>Ixia</strong> test interface can emulate a router gridas large as 200 x 200. In addition, links and routes can beflapped to dynamically assess how the router will behaveunder adverse network conditions.Multi-Protocol Support<strong>Ixia</strong>’s family of emulation software can be run simultaneouslyon one or many ports in conjunction with line-rate traffic tosimulate realistic network scenarios. For MPLS/RSVP-TEtesting, <strong>OSPF</strong> Traffic Engineering LSAs can be injected intoa System Under Test (SUT) to create realistic MPLSconfigurations (<strong>OSPF</strong>v2 only). In addition, custom TLVencoding can be used to create various scenarios.Integrated Testing<strong>Ixia</strong>’s <strong>OSPF</strong> <strong>Emulation</strong> <strong>Software</strong> is installed as an add-on toIxNetwork, <strong>Ixia</strong>’s Graphical User Interface (GUI) applicationfor data and control plane testing. The IxNetwork software exposes many of the packet parameters so thatcomplex IP packets can be created. Traffic streams to advertised routes can be automatically created with anautomated stream generation tool. Traffic statistics can be logged and graphed. In addition, <strong>OSPF</strong> encodes areavailable to facilitate negative state and session testing.Easy-to-Use InterfaceThe IxNetwork GUI facilitates the quick and easy configuration of routing protocol emulations. Configurationwizards provide a simple, graphical-based step-by-step process for initial setup of small to large scale testtopologies across multiple <strong>Ixia</strong> test ports. Wizards are available for <strong>OSPF</strong> specific emulation as well as morecomplex Layer 2 and Layer 3 MPLS VPNs which may use <strong>OSPF</strong>. In addition, IxNetwork’s spreadsheet GUIparadigm provides for the entry, editing, and viewing of large configurations across multiple test ports.Spreadsheet-like commands are available to quickly scalea configuration or apply operations across multiple values.Once a network topology is created, it can be copied easilyacross any supported <strong>Ixia</strong> test port.Tcl AutomationAutomated scripts can be quickly created using the <strong>Ixia</strong> TclAutomation Environment. Alternatively, the IxNetwork GUIcan be used to set up a test configuration, then <strong>Ixia</strong>’sScriptGen utility used to translate the GUI settings to Tclcode with minimal commands. Tcl support is available onWindows, Linux and UNIX platforms.Page 3
