    Creating Topologies with the Topology Wizard

    To use the Topology Wizard to create a new topology:

    1. From the navigation tree, select Topologies > Create Topology in Wizard. The Topology Wizard appears, with the Create Topology dialog box displayed.

      Figure 1: Create Topology Dialog Box

    2. Enter the name of the topology and a description, if desired.
    3. Indicate whether the topology is to be downloadable, savable, or both.
    4. Select the library in which you want to create the topology. Use the filtering fields to narrow your search, if necessary.
    5. Click Create.

      The Topology Wizard window opens in Junosphere with icons and tools on the left side.

      Note: If this is your first time creating a topology, a Required Settings dialog box appears asking you to enable downloads from

      • To see the different types of virtual machine (VM) images, click the double arrow for each type.
      • To see additional information about each image, place your mouse pointer on the image until a tooltip, similar to that shown in Figure 2, appears.

    6. Drag and drop icons for specific types of nodes from the icon gallery onto the canvas, or double-click an icon and then click anywhere on the canvas to place the icon.
    7. To create connections, click the Connector icon and hover the cursor over the center of one of the objects that you want to connect until a hand icon appears and the selected element is surrounded by a green box.

      Note: Do not connect the following VMs to other VMs because they are not network elements. These VM types are used only for network management and planning purposes:

      • Junos Space
      • CentOS
      • Mu Studio
      • Cariden Mate
      • BGP Feed
      • Puppet Master
    8. Enable “T” connections by creating a connection between a network element and the bridge linking the two VMs. The bridge is represented graphically as a circle with a label such as p0, p1, p2, and so on. There is no limit to the number of elements that can be connected to a bridge.
    9. Click Save to save the topology in the library. You can also click Save to File to download a copy of the topology for future use.

      Note: In addition to saving the topology to a sandbox or file, the Topology Wizard has an auto-save feature that saves every five changes made to the topology diagram. These changes can include new VMs added, new links added, VMs removed, links removed, VMs moved, and other changes. The topology is automatically saved to the selected library.

      Junosphere automatically logs out of the Topology Wizard after 30 minutes of being idle. If you are working in the Topology Wizard, you might lose work if you have not saved your changes. Although Junosphere automatically saves work in the topology wizard after every five changes made while creating the topology, it is best practice to manually save your changes as frequently as possible, especially if you are making many changes with a single action.

      If you click Save, a dialog box appears, enabling you to launch your topology directly from the Topology Wizard. See Starting a Topology from the Topology Wizard.

    10. Create a .config file for any configurable network elements in the topology by right-clicking a VM in the topology and selecting Edit VM Configuration from the pop-up menu. A dialog box similar to the following appears.

      Figure 3: Edit Configuration Dialog Box

    11. Either type the configuration information in the dialog box or copy and paste configuration information from another source.
    12. Click Save.

    Note: When creating a topology, the Maximum Transmission Unit (MTU) in the VJX interface must be set to 1500. Otherwise, it cannot route BGP packets.
