Step 1: Determine the Routing Engine Mastership By Checking Status

Action

To determine Routing Engine mastership, use the following CLI command:

user@host> show chassis routing-engine

Sample Output

user@host> show chassis routing-engine

Routing Engine status:

  Slot 0:

    Current state                  Master

    Election priority              Master (default)

    Temperature                 29 degrees C / 84 degrees F

    DRAM                      2048 MB

    Memory utilization          11 percent

    CPU utilization:

      User                       0 percent

      Background                 0 percent

      Kernel                     2 percent

      Interrupt                  0 percent

      Idle                      98 percent

    Model                          RE-3.0

    Serial ID                      P10865701859

    Start time                     2004-04-15 18:45:12 UTC

    Uptime                        6 days, 3 hours, 56 minutes, 8 seconds

Routing Engine status:

  Slot 1:

    Current state                  Backup

    Election priority              Backup (default)

    Temperature                 26 degrees C / 78 degrees F

    DRAM                      2048 MB

    Memory utilization          10 percent

    CPU utilization:
