12.4 VRRP CONFIGURATION NOTES
•
The Master router sends keep-alive advertisements. The frequency of these keep-alive
advertisements is determined by setting the Advertisement interval parameter. The default value is
1 second.
•
If a Backup router doesn’t receive a keep-alive advertisement from the current Master within a
certain period of time, it will transition to the Master state and start sending advertisements itself.
The amount of time that a Backup router will wait before it becomes the new Master is based on the
following equation:
Master-down-interval = (3 * advertisement-interval) + skew-time
The skew-time depends on the Backup router's configured priority:
