Hello muare,
As per rfc4666(rfc3332 is obsolete) said,:
When using DE mode, the management of the connection in the two directions is considered independent, it could happen that only one of the two directions is activated or closed, while the other remains in the same state as it was.
When using SE mode, only the activation phase (ASPTM) is independent for each of the two directions. In this case, it could happen that the sending of the ASPSM from IPSP-A to IPSP-B could have an effect in the whole communication.
Therefore, if you want to two side independent, you should use DE mode.
Best regards,
Zhou Minggang
