Sorry for the spam if this is a 2nd copy of the email. I didn't see this email in my mail yet nor the ipv6 archives. Suresh or Tatuya, please reply.

Thanks so much for providing the para. Now I have a separate question to you folks. What IPv6 network has an interface receiving an NA where the target address in the NA matched an assigned address on the receiving interface given the fact the address that matched is not tentative? Also, once this situation happens, why is it not a DAD failure and hence logged with an error message rather than a silent discard? Thanks.

The old para in section 5.4.4 On receipt of a valid Neighbor Advertisement message on an interface, node behavior depends on whether the target address is tentative or matches a unicast or anycast address assigned to the interface. If the target address is assigned to the receiving interface, the solicitation is processed as described in [I-D.ietf-ipv6-2461bis]. If the target address is tentative, the tentative address is not unique. will be replaced with the new paragraph On receipt of a valid Neighbor Advertisement message on an interface, node behavior depends on whether the target address is tentative or matches a unicast or anycast address assigned to the interface. If the target address is assigned to the receiving interface, the advertisement SHOULD be silently discarded. If the target address is tentative, the tentative address is not unique. Since there is no text in 2461bis to directly handle this condition, I believe that the suggested text makes sense.
