Document: draft-mglt-ipsecme-clone-ike-sa-05.txt Cloning IKE SA in the Internet Key Exchange Protocol Version 2 (IKEv2) Reviewer: Joel M. Halpern Review Date: 2-Oct-2015 IETF LC End Date: 27-Oct-2015 IESG Telechat date: N/A 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. Minor issues: Nits/editorial comments:
