Hi All,

How to handle "Initial Contact Notification" during simultaneous IKEv2 SA negotiation?

For
 example: A pair of gateways are initiating IKEv2 negotiation almost at 
the same time resulting in 2 sets of IKEv2 SAs. In IKE_AUTH, both the 
boxes are sending "Initial Contact" notification and IKE_AUTH almost 
cross each other. On receiving the IC, if both try to delete the other 
IKE SAs on the box, we end up having different sets of IKE & child 
SAs on the both sides.


Thanks
Kanaga.
