Thanks for your patience. Hoping that you can still accept this
one:-), here is one more related thing:
2461bis-03 (more accurately since 2461bis-01) has a new paragraph in
Section 7.2.5:
In any state, if the link layer has addresses and an unsolicited
Neighbor Advertisement is received with the O flag cleared, with no
Target Link-Layer address option included, the receiving node SHOULD
silently discard the received advertisement.
(the 3rd paragraph of this section)
The corresponding part of original RFC2462 should be the following
line:
[If the target's Neighbor Cache entry is in the INCOMPLETE state when
the advertisement is received, one of two things happens.] If the
link layer has addresses and no Target Link-Layer address option is
included, the receiving node SHOULD silently discard the received
advertisement.
As far as I can see, the new text is more than just a "clarification".
In the new text,
- the rule is applied to all neighbor cache states. (in original
RFC2461, it was limited to the INCOMPLETE state)
- a new condition about the O flag is added
So I guess there should have been a clear reason for the new text. If
it was, what was that? Or, if there was actually no special reason
(or we cannot even remember that), it would be another reason for
changing it back (for "safety").
