Well, this was to mean conforming to the "IP Version 6 Addressing Architecture" (RFC 4291). Will try to be even more precise next time! > By means of the V-octet, seeking to "appropriate" a part of all v6 address > space for 4rd, It seems that, if you did read 4rd-03, you misunderstood the top of page 20. it explains that nothing more than routing on prefixes as usual is needed to reach CE functions. If I misunderstood your point about "appropriate a part of all v6 addresses", thanks for explaining. > or any other device class to deal with a remote case of a > duplicate, which may still happen, seems overdone. > In any case this looks > to be a 6man consideration. Same answer as to Ole: "6man has to be involved, sure, but Softwire should first be clear about the purpose, and possible drawbacks if any."
