Abstract: A method for Internet Key Exchange (IKE) re-authentication optimization includes sending, by a first network device and a second network device, a notification, which contains new Security Parameters Index (SPI) for new security association (SA), and sending, by the first network device alone, an OLD_SPI notification to map SPI of Internet Protocol Security (IPsec) (Authentication Header (AH)/Encapsulating Security Payload (ESP)) with the old IPSec SA.
