Step 8: Download JUNOS Software

NOTE: To download the JUNOS software packages, you must have a service contract and an access account. Try to download the software packages a few days before you intend to install them, as you may need to verify your service contract and access account. If you need help obtaining an account, contact your Juniper Networks sales representative or send an e-mail to logistics@juniper.net.

What It Means

Each JUNOS software release consists of the following software packages:

• jbase—Additions to the operating system
• jkernel—Operating system package
• jroute—Software that runs on the Routing Engine
• jpfe—Software that runs on the Packet Forwarding Engine
• jdocs—Documentation for the software
• jcrypto—Security software (in domestic software only)

The packages are also grouped together in a bundle, called jbundle. Normally, you use the bundle to upgrade all of the software packages at the same time.

NOTE: If you are upgrading to Release 5.0 from Release 4.x or downgrading from Release 5.0 to Release 4.x, use the jinstall package. Otherwise, use the jbundle package to upgrade to a new release. Downgrading from Release 5.0 to Release 4.x can be a two-step process. For more information, see JUNOS Internet Software System Basics Configuration Guide.

You also can upgrade the software packages individually but this is not recommended. When upgrading to a new release, you must install the entire bundle; do not upgrade packages individually unless instructed to do so by the Juniper Networks Technical Assistance Center (JTAC).

Two sets of JUNOS software packages are provided: one for customers in the United States and Canada, and another for worldwide customers. The worldwide version does not include any capabilities that provide encryption of data leaving the router. Otherwise, the two packages are identical.
