IKE_SA SPI with a changed address

[Corrado Derenale <derenale@polito.it>]

Dear all,

what would happen in IKEv2 if the  Initiator and Responder change their 
IP adresses after have established an IKE_SA?

It is still possible refernce the SAD with the SPI (the IKE_SA SPI) 
found in the CREATE_CHILS_SA header in order to retrieve the parametres 
to generate a new CHILD_SA?

Thanks,
