Hi Yiu 4rd-u changes the IPv6 header architecture (redefine fragmentation header extension) and IPv6 address architecture (different meaning of u-bit when g-bit=1). These are the fundamental changes. If 4rd-u becomes the standard, then there will be new defined “IPv6” packets on the Internet, which are not compatible with existing IPv6 packets and no existing devices can understand those packets.
