Cloning IKE SA in the Internet Key Exchange Protocol Version 2 (IKEv2)

Summary: This document is nearly ready for publication as a Propsoed 


Standard RFC.




Major issues:


    The introductory material talks about the case where both sides 


have multiple interfaces.  It is not clear what will happen with this 


mechanism in that case.


    In particular, if I have two systems, with three interfaces, it 


seems that this will start by creating the S1-D1 Security Association. 


It seems straightforward for each side to create their simple additional 


assocations (S2-D1, S3-D1, and S1-D2, S1-D3).


    But the introduction suggests that we also want to create S2-D2, 


S3-D3, S2-D3, and S3-D2.  With no other guidance, it appears that both 


sides will try to create all four of those, creating 8 security 


associations instead of 4.


    I hope that I have simply missed something in the document that 


resolves this.
