Selecting an Advertisement Interval

In most cases, leaving the Advertisement Interval to its default value of 1 is adequate. Usually, this is also desired because it will allow for the fastest fail over time. As described above, the time a Backup will become Master if it stops receiving advertisements is approximately three times this value in seconds. A higher value may be selected if the network is very stable and less advertisement traffic is desired. In any case, it is not recommended that the interval be increased to values above five or six.
