Network Working Group R. Wakikawa, Ed. Request for Comments: 5648 Toyota ITC Category: Standards Track V. Devarapalli Wichorus G. Tsirtsis Qualcomm T. Ernst INRIA K. Nagami INTEC NetCore October 2009 Multiple Care-of Addresses Registration Abstract According to the current Mobile IPv6 specification, a mobile node may have several care-of addresses but only one, called the primary care-of address, can be registered with its home agent and the correspondent nodes. However, for matters of cost, bandwidth, delay, etc, it is useful for the mobile node to get Internet access through multiple accesses simultaneously, in which case the mobile node would be configured with multiple active IPv6 care-of addresses. This document proposes extensions to the Mobile IPv6 protocol to register and use multiple care-of addresses. The extensions proposed in this document can be used by mobile routers using the NEMO (Network Mobility) Basic Support protocol as well. Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
