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

    https://www.juniper.net/documentation/us/en/software/junos/static-routing/topics/ref/command/show-route-summary.html

    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.

    I'm sure you've long since worked out the correct answer, but it was 20.2 that introduced it, hence the change in your CLI output.

    System Logging

    • Support to track the maximum number of routing and forwarding (RIB/FIB) routes and VRFs (MX Series and PTX Series)-Starting in Junos OS Release 20.2R1, you can track and display the high-water mark data of routing and forwarding (RIB/FIB) table routes and VRFs in a system (RPD) using the show route summary CLI command. High-water mark refers to the maximum number of routing and forwarding (RIB/FIB) table routes and VRFs that was present in the RPD system. The high-water mark data can also be viewed in the syslog at the LOG_NOTICE level.

      You can configure the interval of the high-water mark data using the highwatermark-log-interval CLI configuration statement at the [edit routing-options] hierarchy level. The minimum time gap at which the high-water mark data logged in the syslog is 30 seconds. You can configure the value for highwatermark-log-interval CLI configuration statement between 5 to 1200 seconds.

    Your quote as I expected. So it is the highest record on RIB/FIB routes since the device is turned on. I was getting messed up with "watermark" words. Thank you.
