What I am trying to say and this is very confusing is that CISCO and other BSD Linux based OS don’t have the ability to check for valid IPv6 global unicast or link local configuration that it is following the RFC Standards as with IPv4. So just because it works does not mean it is correct or ok or that the standards should now change because it works on various OSs that are not following the RFC that we now chant to make that now ok and standard. We need more justification then that to change the standards. In one of the other threads I mentioned that if we are trying to improve or enhance the standard because we have valid future user cases that would require having a new “subnet id” 54 bit field then it’s ok as we are improving with newer RFC revision making the older one obsolete. For backwards compatibility the all’s 0s 54 bits would be for legacy devices supporting RFC 4291 so they are not impacted and anything on newer coder can now look at supporting the new RFC.
