Junos Continuity Software Overview
Junos Continuity is a software package that enables you to deploy new hardware in the network without the need to upgrade Juniper Networks Junos operating system (Junos OS). Junos Continuity software works like a pluggable software module that enables you to deploy new hardware by providing the drivers and support files required to bring the hardware online. Each version of the Junos Continuity software package supports a specific type of hardware, such as Modular Port Concentrators (MPCs), power supply modules, and so on. You can download and install the Junos Continuity software package that supports the hardware component that you want to deploy.
You can install Junos Continuity software to add support for new hardware on elected releases of Junos OS. An elected release is a maintenance release of Junos OS, which supports Junos Continuity software. You need to download the Junos Continuity software package that is specific to the elected release.
Junos Continuity software standalone package is supported only on the MX240, MX480, MX960, and MX2000 Universal Routing Platforms.
You install the Junos Continuity software package to enable a router to support new hardware without the need to upgrade Junos OS. You can install the Junos Continuity software package as a standalone package or as a package bundled with Junos OS.
Install the Standalone Junos Continuity Plug-in—You install the Standalone Junos Continuity Plug-in if the version of Junos OS that is installed on the router supports Junos Continuity software.
Install the Junos Continuity Plug-in Integrated with Junos OS—You use the integrated package if the version of Junos OS that is installed on the router does not support the Standalone Junos Continuity Plug-in. For example, if you want to install Junos Continuity software on Junos OS Release 13.3, you can use the integrated package that contains both Junos OS Release 15.1F4 and the Junos Continuity Plug-in. This is a one-step process to upgrade Junos OS to Junos OS Release 15.1F4 and also to install Junos Continuity software.
