Scenario:

Assuming the Tunnel built successfully but there are some traffic/unstable/disconnecting issues.

Checking:

1)Reauth action must ahead of Rekey, Please check phase1 lifetime greater than phase2.

2)Recommend to use ikev2 beacuse it implements a more complete rekey mechanism to prevent tunnel reconect.
