Dear Rashid Sangi. Thanks for your contribution.
I read your draft and it is interesting. I would like to deliver my comments. 1. IID Assignment by 6LBR When I extended Mobile IPv6, I also thought that a router can perform movement detection, formulates a new CoA of the MN and does Duplicate Address Detection (DAD) on behalf of the MN ( https://datatracker.ietf.org/doc/draft-hong-mobileip-acar/). Unfortunately, this works did not continue. Until now, generating IIDs depends on the nature of networks and link layer technologies. In the constrained environments, IID of each device are heterogeneous. In this situation, IID assignment by 6LBR may have pros and cons. It is better to describe the pros and cons more detail. I am wondering how to provide backward compatibility to legacy devices that use conventional generating IIDs. 2. Mismatch of main body texts and figure In figure 1, "Randomized Secret Key" is used but "Randomized Private Key" is used in the main body texts. Is it same or different? Best regards. Yong-Geun.
