The decision of the Junos OS package is taken based on the needs of the Network, for that reason is important that the client knows what they need to accomplish.The following information will make the decision easier for you based on the Network’s needs.
This is a short recap of the meaning of the Junos OS packages:
This version has no cryptographic support and is intended for countries in the Eurasian Customs Union (EACU). These countries have import restrictions on software containing data-plane encryption.
(EACU is currently comprised of Armenia, Belarus, Kazakhstan, Kyrgyzstan, and Russia)
The “Junos Limited” image does not have data-plane encryption and is intended only for countries in the Eurasian Customs Union because these countries have import restrictions on software containing data plane encryption.
This is the normal Junos version, it doesn't allow you to run unsigned programs.
This software bundle is identical to the other software bundle (QFX 5e Series Switch), except that Veriexec is disabled, which enables you to run unsigned programs, such as programs that you develop with Python, Chef, and Puppet.
The Junos Automation Enhancements include the following features:
• The factory default configuration is a Layer 3 configuration. (The standard default factory configuration on some device series is Layer 2.)

• The installation automatically sets up and reserves a 1 GB user partition on your system. You can use this partition to store your binaries and additional packages.
• The user partition is not overwritten when you upgrade or downgrade the software to a OS image that does not contain the automation enhancements.
