DETAILED STEPS
Specifying Keepalive Intervals
The keepalive interval is the period of time between keepalive messages sent by a network device. A
keepalive message is a message sent by one network device to inform another network device that the
virtual circuit between the two is still active.
Note
If you plan to use the default time interval between messages, which is 30 seconds, you do not have to
perform this task.
