Installing Junos OS Licenses on Virtual Chassis Member Routers

To enable some Junos OS features or router scaling levels, you might have to purchase, install, and manage separate software license packs. The presence on the router of the appropriate software license keys (passwords) determines whether you can configure and use certain features or configure a feature to a predetermined scale.

Before you configure an MX Series Virtual Chassis, install the following Junos OS software licenses on each MX Series router to be configured as a member of the Virtual Chassis:

  • MX Virtual Chassis Redundancy Feature Pack—You must purchase and install a unique MX Virtual Chassis Redundancy Feature Pack for each member router in the Virtual Chassis. If you issue the request virtual-chassis member-id set, request virtual-chassis member-id delete, request virtual-chassis vc-port set, or request virtual-chassis vc-port delete command to set or delete member IDs or Virtual Chassis ports without first installing an MX Virtual Chassis Redundancy Feature Pack on both member routers, the software displays a warning message that you are operating without a valid Virtual Chassis software license.
  • Junos OS feature licenses—Purchase and install the appropriate Junos OS feature licenses to enable use of a particular software feature or scaling level in your network. You must install the required feature licenses on each member router in the Virtual Chassis.

Before you begin:

To install Junos OS licenses on each member router in the Virtual Chassis:

  1. Install the required licenses on the MX Series router to be designated as the protocol master for the Virtual Chassis.
    1. Install the MX Virtual Chassis Redundancy Feature Pack.
    2. Install the Junos OS feature licenses required for your software feature or scaling level.
  2. Install the required licenses on the MX Series router to be designated as the protocol backup for the Virtual Chassis.
    1. Install the MX Virtual Chassis Redundancy Feature Pack.
    2. Install the Junos OS feature licenses required for your software feature or scaling level.
  3. (Optional) Verify the license installation on each member router.

    For example:
