    This displays the maximum routes that hit the high water mark for the device.

    The percentage level appears to be set at 100% by default

    Hi Spuluka. Thanks for the reply. I'm using MX80. But I don't think I have made a configuration just like as you share the page. On previously it has no watermark on "show route summary"

    xxx@xxx> show route summary | no-more 
    29 Apr 2022 10:13:17
    Autonomous system number: xxx
    Router ID: xxx.xxx.xxx.xxx
    
    inet.0: xxx destinations, xxx routes (xxx active, xxx holddown, xxx hidden)
    ....​

    It snap was on 3 months ago.  I just did the upgrade Junos from 17.3R3-S7.2 to 20.2R3-S4.7. Are those affected to the shown of watermark?

    The way I read the documentation, the line will only appear after the high water mark threshold is actually reached for the device since the last reboot.
