the interval in the advertisement. If the backup does not receive a new VRRP advertisement from the master when the timer (3 × recorded interval + Skew_Time) expires, it regards the master as failed and takes over as the master. Large network traffic might disable a backup from receiving VRRP advertisements from the master within the specified time and trigger an unexpected master switchover. To solve this problem, you can use this command to configure a larger interval.
