[…] I found it confusing at first too, but the RFC 2119 keyword language in RFC 4862 is pretty unambiguous, and it makes sense too if you think about PIO updates that only change the lifetimes and the value of the A flag. The requirement to drop all PIO with invalid prefix length for the link type, regardless of the A flag, ensures with a simple-to-implement rule that you never take a misconfigured prefix as on-link if you cannot ever auto-configure an address in the prefix when the update to A=1 arrives. This may not be the behavior you’d prefer that RFC 4862 require, but the requirement is clearly there and certification tests are within their ambit to check for it. Moreover, this proposed successor to RFC 4291 doesn’t even have an informative reference to RFC 4862 in it, much less an explicitly declared update. And I don’t believe it should. --james woodyatt <jhw@google.com <mailto:jhw@google.com>>
