It is an optional software package that enables the MX routers (MX240, MX480, MX960, MX2010 and MX2020) to support new hardware (e.g. MPC) without upgrading Junos OS. This helps faster deployment of the new hardware and eliminates the time required for software re-qualification that is required when you upgrade the OS.|
