  2. Status • Draft finished WG LC with comments. • Most comments were editorial. • Major issue about the interaction between DSMIPv6 and IKEv2. • No consensus within the WG, therefore the security review resulted in the selection of a solution. No objections were raised after the security review. • Selected approach: Use RFC 3498 for SA establishment and for sending secure payload. Use DSMIPv6 tunnel to send BU/BA as described in the draft. • Assumption: UDP tunneling is NEVER used when the MN is in an IPv6-enabled network. • The use of Mobike is optional. • Issue addressed in the security considerations section in the draft after going through WG consensus.

  3. Comments on the Security considerations section • Comment from Karen: Update of local SA in the MN should only be done after the receipt of the BA. • Comment from Karen: Mention that the type of tunnel SA may change from RFC4301 type tunneling to RFC 3498 (depending on whether a NAT is in the path) • Comment from Pasi: Mention that this NAT traversal solution has the same vulnerabilities as RFC 3519 and not UNSAF vulnerabilities (current draft mentions UNSAF). • Comment from Pasi, George, Vijay: The MN SHOULD deregister its RO BCEs with CNs when it moves from an IPv6 network to an IPv4 network. • Several editorial comments from George.

  4. Next steps • Send a new security considerations section to the list after updating it based on the comments. This should happen ASAP. • Progress the draft to IESG?
