The IESG has approved the following document: - 'MIP6-bootstrapping for the Integrated Scenario ' <draft-ietf-mip6-bootstrapping-integrated-dhc-06.txt> as a Proposed Standard This document is the product of the Mobility for IPv6 Working Group. The IESG contact persons are Jari Arkko and Mark Townsley. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-mip6-bootstrapping-integrated-dhc-06.txt Technical Summary Mobile IPv6 bootstrapping can be categorized into two primary scenarios, the split scenario and the integrated scenario. In the split scenario, the mobile node's mobility service is authorized by a different service authorizer than the network access authorizer. In the the integrated scenario, the mobile node's mobility service is authorized by the same service authorizer as the network access service authorizer. This document defines a method for home agent information discovery for the integrated scenario Working Group Summary The design team had some differences regarding the integrated scenario and use of DHCP as a means for bootstrapping. However these issues have subsequently been clarified. The current I-D in a previous version included several DHCP options which are required for bootstrapping. These have now been specified in a separate I-D (draft-ietf-mip6-hiopt-03.txt). This I-D is dependent on the DHCP options specified in the companion MIP6 WG Doc: draft-ietf-mip6-hiopt-03.txt The specification has also been reviewed in the DHC WG. The completion of this waited until the companion document was also revised according to the review issues from DHC WG. Protocol Quality This specification has been reviewed by Jari Arkko for the IESG. A review from the Mobility Directorate has been requested. A last call in the DHC WG has been performed. No known implementations of this protocol exist at the current time. However some vendors have indicated plans to implement this specification. This specification is also of interest in other SDOs such as 3GPP2 and WiMAX forum. Note to RFC Editor Insert the following text to the third paragraph of Section 1, after the paragraph's first sentence: In the integrated scenario, the bootstrapping of the home agent information can be achieved via DHCPv6. The motivation for using DHCPv6 is to let the network assign the home agent to the MN when the MN performs network access authentication with the Access Service Authorizer which is also the Mobility Service Authorizer of the MN (integrated scenario). The Mobility Service Authorizer assigns the home agent information for the MN via AAA transaction with the NAS. The MN can retrieve the assigned home agent information using DHCPv6 subsequently. Please replace the Security Considerations section with this: The transport of the assigned home agent information from the AAA server to the MN entails carrying this information in the form of AAA and DHCP payloads. Integrity and privacy protection of home agent information as it is delivered from home AAA server to the AAA client (NAS) in the form of a AAA attribute/AVP is described in [MIP6-RADIUS] for RADIUS and [MIP6-Dime] for Diameter. Similarly, [HIOPT] describes the integrity and privacy of this information as it is delivered from DHCP relay (NAS) to DHCP server to DHCP client in the form of a DHCP option. This protocol inherits security considerations from RFCs 3775, 4640, and [BOOT-SPLIT]. _______________________________________________ IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
