Hi All, I am now reading "draft-ietf-mobileip-ipv6-16.txt".
My questions are as follows: 1. Am I reading the latest draft? 2.Is it necessary to have a Home Address Option, since the Binding Update Destination Option already has a Home Address field which gives the home address of the mobile node? It will be redundant for the Binding Update to include a Home Address Option, why there is the redundancy? 3.It is stated in section 5.1.6 of the draft that: "A Binding Update message to the correspondent node MUST NOT include the Home Address option in order to avoid reflection attacks..." which contradicts the statement made in section 8.2 that: "Before accepting a Binding Update option received in any packet, the receiving node MUST validate the Binding Update according to the following tests: -... - The packet MUST contain a Home Address option. ..." If both statements are true, according to them, all Binding Updates sent to the correspondent node (not including the home agent) will be discarded. What's wrong? Thanks!
