Excuse me for not doing this earlier, but I finally check the 05 version to see my previous comments were addressed, and found some points I'm not sure about.

Has that version been issued, or is the version number bumped?) I've compared the difference of the state machine in Appendix C between the 03 and 05 versions (attached below). At least it doesn't seem to cover the case where the neighbor cache entry does not exist. It also does not cover the case where a Redirect message (w/o target link-layer address option) caused the situation in question. In addition, I don't understand the following entry (added in 05): + INCOMPLETE NA, Solicited=any, Send ICMP error unchanged + Override=any, No (if router) or + Link-layer address log error (if host) + Which ICMP error is expected to be sent in this case? Why do we separate the case for router and host? These points are probably pretty minor, and we can probably deal with those in concurrent with the AD/IESG evaluation, though.
