Chassis Clustering - IP Monitoring

    Hi,
    I'm having hard time to comprehend with this explanation from chassis clustering section of JSEC course. Is there anyone who can lighten up the phrases?
    I understand how interface monitoring works, its a straightforward approach. When an interface fails, its weight (255) will be subtracted from the global weight of 255 and cause the RG to failover to the secondary node in the cluster.
    Unfortunately in IP monitoring, I can't understand what the author is up to. I am getting confused why they used 200 for global-weight value, 120 for global-threshold value and 100 for monitored address weight value.
    Global-threshold of 120 subtracted to monitored address weight of 100 is not equal to 0. (120-100 is not equal to zero). This makes the explanation more complicated.
    Please see the attached screenshot from Juniper Tech guides and JSEC course module.

    Hi, 

    I think this is the same question you posted under SECURITY.

    I answered your question there:
