I read the following and interpreted the draft proposed a solution that addressed the identified shortcomings of x-MIP draft. draft-devarapalli-mip4-mobike-connectivity-00.txt: "There has been some work done on using Mobile IPv4 and IPsec VPNs to provide roaming and secure connectivity to an enterprise [10]. The solution described in [10] was designed with certain restrictions, including requiring no modifications to the VPN gateways and involves the use of two layers of MIPv4, with one Home Agent inside the intranet and one in the Internet or in the DMZ before the VPN gateway. The per-packet overhead is very high in this solution. It is also challenging to implement and have two instances of MIPv4 active at the same time on a mobile node. This document describes an alternate solution that does not require two layers of MIPv4. " Then later, I see your clarification stated later. OK. "The solution described in this document uses Mobile IPv4 when the mobile node is on the trusted network and MOBIKE capable IPsec VPNs when mobile node is on the untrusted network. " > however, I would support an effort to define requirements for > a more optimal solution involving MIPv4 and *any kind* of VPN > gateway and encourage MIPv4 WG to look into an optimal solution. > OK. Should this draft be under the scope of such general solution? A IKEv2/MOBIKE VPN GW is a specific type of "any kind" of VPN GW, right? :) Kent -- Mip4 mailing list: Mip4@ietf.org Web interface: https://www1.ietf.org/mailman/listinfo/mip4 Charter page: http://www.ietf.org/html.charters/mip4-charter.html Supplemental site: http://www.mip4.org/
