Abstract
The present invention provides a method and a system for negotiation based on IKE messages. A standby device updates a value of a stored third identity according to an update notification of an active device. The update notification of the active device is sent by the active device after updating a value of a stored second identity. When the standby device switches to a new active device, the new active device sends a second message for negotiating IPSec information to a peer device according to the updated third identity. The third identity is an identity that is stored in the standby device and used to acquire state information of the active device.
