    if we can make sure that the keepalived/conntrackd are running when the VR becomes Running.
    I think the sleep is needed, no matter we destroy/create backup or master router at first,
because there is always a state change from BACKUP to MASTER.
    
    in your method, the sleep is not needed at the first step, but it does at the second step.
