Example:
The Keep Alive interval is set to 5 seconds. That is, every 5 seconds an alive
signal is sent out to all neighboring V Switches. The neighboring V
Switches register a suspicious interval after 10 seconds without an alive
signal. This is the equivalent of 2 missed keep alive intervals. After a total
of 20 seconds, from the first missed alive signal, the neighboring V Switches
register a dead interval. This is the equivalent of 4 missed keep alive
intervals.
