IPv4/IPv6 transition 5 min Chairs Questions about MIPv4/MIPv6 - IPv4/IPv6 transitions

3012bis Issue was raised with HMAC_CHAP_SPI Proposed Resolution Inner HMAC for compression would require a key No pre-shared key between MN and FA No way to carry this inside RADIUS RADIUS servers implement CHAP, not HMAC_CHAP Proposed Resolution Delete HMAC_CHAP_SPI from text It was added after security review suggested replacing MD5 with HMAC_MD5 However, review was really talking about the main authentication extension, not the RADIUS compatibility text We have a disclaimer about the safety of this option in the Security Considerations

VPN Solution draft-ietf-mobileip-vpn-problem-solution-03.txt Sami Vaarala is the current editor Sami has agreed to continue, but doesn’t have a lot of time… A co-editor is needed Last IETF, some people offered to work on this Please see the chairs after the session so we can finalize this

3344bis Charlie Perkins

Foreign Agent Error Last Call ended Friday, Nov 5 One comment received Positive support Length field correction What to do about unauthenticated FA error? What to do if FA receives RRP with FA error already appended? Discuss here, resolve on the list Do we have support to move forward?

Route Optimization Do we want to take this on? It was a major source of contention in IPv6! There is a not inconsiderable amount of work required to specify this as a general mechanism which will have acceptable security… Who are the customers? What are the assumptions? Security model?

IPv4/IPv6 Transition A new mailing list has been created miptrans@ops.ietf.org Purpose: discussion of IPv4/IPv6 transition questions related to Mobile IP To subscribe: send “subscribe miptrans” in the body of an e-mail to majordomo@psg.com

IPv4/IPv6 Transition draft-larsson-v6ops-mip-scenarios-00 Individual submission Will be submitted directly to the IESG for publication Attempts to define the field of possible combinations of IPv4/IPv6/MIP4/MIP6 Getting acceptance for specific solutions has been difficult Comprehensive analysis like this needed first Analysis in draft may be basis for future work Comments welcome Please discuss on miptrans@ops.ietf.org

IPv4/IPv6 Transition Requirement for new MIP4 work items in this space: A clear statement of the scenario / environment for which this is needed A clear statement of which of parts of the transition combinations will be addressed A definition of the problem, e.g. why does the work need to be done
