    Building and Testing Your Network Topology

    After you have completed the configuration of your virtual network, perform the following tasks:

    Building a Topology File Set

    The process for building a topology file set depends on your operating system. Windows users can use WinZip or another Windows-based compression tool to create .zip files.

    UNIX and Linux users can build a topology file set with a .tgz extension by performing the following steps:

    1. Create the directory structure specified below:
      • <home>/active/
      • <home>/active/configset/
    2. Add topology.vmm, the VMM configuration file that defines the topology, to the active directory.
    3. Add the Junos OS configuration files for each network device referenced by topology.vmm to the <home>/active/configset/ directory.
    4. Create a topology file set, suitable for submission, by doing the following for .tgz file types:
      1. Change to the <home>/active/ directory.

        cd <home>/active

      2. Tar the files.

        tar –cvf mytopology.tar *

      3. Zip the files.

        gzip mytopology.tar

      This creates the mytopology.tar.gz file.

    5. Change the extension on the file from mytopology.tar.gz to mytopology.tgz.

    Topology file sets must have a .zip or .tgz extension to be uploaded.

    Connecting to the Network Topology

    To connect to the virtual devices in the network topology and work with them:

    1. Select Topologies > Access Active Topologies.
    2. Click the Virtual Machines tab to view the IP address and connection information for the Console port or management Ethernet of the virtual device.

      Note: This information can be copied and pasted into an Excel spreadsheet.

    3. Click Join in the Active Topology section at the top of the screen.

      The Junosphere Access Portal appears.

    4. Enter your username and password and click Sign In.
    5. Click the Network Connect Start button.

      Network Connect establishes a secure access SSL VPN to the internal management Ethernet of the topology. Traffic will be directed only to the local management Ethernet over that tunnel. Network Connect works best without web proxies, but works fine with a static proxy configuration. It will not work, however, if the browser is configured with a PAC (proxy auto-configuration) file.

      Note: You need to have administration rights on your computer to install the Network Connect software.

      You cannot run two simultaneous instances of Network Connect. If you already have one instance of Network Connect running for a corporate VPN, you must stop it before you begin another instance.

    6. Connect to a virtual device using an appropriate communications program. For example:
      • For VJX, use telnet or CMD shell.
      • For CentOS, use VNC. Enter the IP address (with :1 at the end) of the virtual device; enter Clouds as the password.
      • For Junos Space or Mu Studio, open a browser from a virtual CentOS in Junosphere and browse to the IP address.
      • For Spirent, use the Spirent tool.

      For more information, refer to the manual for each VM type.

    7. Log in to the Junos OS virtual device using the default username and password. The default root password is Clouds.
    8. If you are connecting to a Junos OS network device, enter cli to start using the Junos OS environment.

    Just as with a physical Junos OS device, configuration changes are made in edit mode and then committed to implement the changes on the router. To save your changes to the library, click Save on the Junosphere Libraries menu.
