In RFC 2461, section 7.2.2, the first sentence of the third paragraph reads:
"If the solicitation is being sent to a solicited-node multicast address, the sender MUST include its link-layer address (if it has one) as a Source Link-Layer Address option."
I believe this specification is correct, and I interpret the phrase
"(if it has one)" to mean that the SLLAO may be omitted (or,
may contain don't-care values) if the sender does not have a
link-layer address. However, the text of section 7.2.4 ("Sending
Solicited Neighbor Advertisements") does not account for the
case in which the responder does not have a link-layer address.Suggested fix is to change the 4th sentence of the first paragraph of section 7.2.4 to:
"If the solicitation's IP Destination Address is a multicast address, the node MUST include its link-layer address (if it has one) as a Target Link-Layer Address option in the advertisement."
