Software Installation and Upgrade

  • Automatic firmware upgrade during initial boot (MX304)—We support automatically upgrading the firmware for the Flexible PIC Concentrator (FPC) field-programmable gate array (FPGA) component. After you upgrade the software package, during the first boot of the new software, the system checks the version of that component's firmware. If the FPC FPGA firmware version in the router is lower than the version available in the new software, the system automatically installs the new firmware for that component.

  • Enhanced VM host architecture support for new RCB (MX240, MX480, MX960, MX2010, MX2020)—The MX series routers now support the enhanced VM host architecture. The integration of TVP and VM host has resulted in the creation of the enhanced VM host architecture. This architecture segregates platform-dependent, platform-independent components, and guest applications. This approach helps platform and PFE activities happen independent of Junos OS and also allows us to leverage the benefits of open-source software and drivers.
