As an implementor IPv6 stack, I say that I had no problem understanding the L & A bits in prefix announcements. <hs> We are not saying a host implementer cannot get it right. We are saying some don't. We have found a popular host implementation to be blatantly ignoring off-link indication in RA. Further, hosts are most confused for data forwarding and address resolution when no PIO is sent in RA. That is what we focused on in section 2.1 of our I-D. Just have to verify... You are aware about the "onlink assumption when no routers present" rule? Early RFC had some wording about that host must assume any address is onlink, when no routers are present (or was it "when no route for the destination is found, then try assuming it's onlink"). <hs> Please refer to bullet 6, section 2 of our I-D where we discuss this case. The case of a network in which no routers are present is covered by text in the bullet. If no routers are present, the Default Router List will be empty. Our text says "If the Default Router List is empty, the host MUST NOT assume that all destinations are on-link..." The corresponding text has changed from 2461 to 2461bis. We are aware that there are some implementations which may be compliant with 2461 that are not compliant with 2461bis.
