Known Behavior

The following new behaviors are known to occur in NorthStar Controller Release 3.0.0:

  • Use of the supervisorctl restart all command to restart all services can cause a race condition. We recommend the use of the service northstar restart command instead.
  • If you are using a two-VM installation, in which the Junos VM is not bundled with the NorthStar Controller, and if your external Junos VM is older than Release 17.2, you must edit the northstar.cfg file to make the NorthStar Controller compatible with the external VM.

    Note: If you edit the northstar.cfg file to make the NorthStar Controller compatible with an older external VM, segment routing on the NorthStar Controller will no longer be supported.

    Perform the following steps:

    1. SSH to the NorthStar server.
    2. Using a text editor such as vi, edit the following statement in the opt/northstar/data/northstar.cfg file from the default of use_sr=1 to use_sr=0:
      JunosVM ntad version supporting segment routing: No (0) or Yes (1) 
      use_sr=0
    3. Manually restart the toposerver process:
      [root@northstar]# supervisorctl restart northstar:toposerver

      You also need to set up the SSH key for the external VM by selecting option H from the Setup Main Menu when you run the net_setup.py script, and entering the requested information.
