ATIC detects the flow abnormal, but did not issued a diversion route.
In this case the real reason is that the diversion is disabled.
Enter the diversion task management, check the diversion task, it was in the disabled state, enabled the diversion manually and then the problem was solved.
In general as long as the detected anomalies, sure to divert, no divert may be due to the following:
(1) The diversion pattern for the manual mode, the manual confirmation of diversion route to send.
(2) The diversion function is disabled. At this time could not be automatically issued a diversion route.
The diversion is disabled, easy to be ignored. Should pay attention to carefully check.
