Automation

There are two ways to make configuration changes:

• Unstructured
  Unstructured changes are simply snippets of Junos OS configurations in any of the supported formats.  Templates are snippets that have variables, so that you can quickly and easily produce configurations

• Structured
  Structured changes use well-defined Resource abstractions that have a programmatic approach to performing changes and accessing properties.  Resources are analogous to the structured abstractions you would find in IT frameworks such as Puppet and Chef.

You can find specific instructions, including code samples in Configuration Management in Junos PyEZ
