    The topology.vmm File

    After understanding the customer‘s requirements, purpose, and goals for the network, you can define the virtual network topology using Virtual Machine Manager (VMM) language syntax.

    To create a virtual network using the VMM syntax, you need to define the following:

    • .vmm file default headers and syntax components.
    • Definition of each virtual machine, including:
      • The virtual machine name, such as vrouter#, where # is a number.
      • The virtual image to boot that defines the type of virtual machine. (Refer to the Junosphere Release Notes 3.0 for a complete list of supported images.) You can also view a list of supported images in Junopsphere by selecting Configuration > View VM Images in the navigation tree.
      • Virtual machine interfaces to map.
      • A link to a configuration file (optional).
    • The connections between the virtual machines (VMs).
      • To connect interfaces between two virtual machines, define them to be on the same bridge.
    • Optional comments.

    A topology file set is a compressed file (.zip or .tgz) that has the structure shown in Figure 1.

    Note: To create the topology.vmm file, use any text editor. To integrate or to open files in your file set, use 7zip (for zip compression) or any compression tool to create a zip/tgz compression).
