The following errata report has been submitted for RFC6145,
"IP/ICMP Translation Algorithm".

--------------------------------------
Type: Technical
Reported by: Gandhar Gokhale <[email-masked]>

Section: 5.1

Original Text
-------------
<Removed from RFC 2765 where it had existed after Destination Address field description> 

Corrected Text
--------------
If any of an IPv6 Hop-by-Hop Options header, Destination Options  header, or Routing header with the Segments Left field equal to zero  are present in the IPv6 packet, those IPv6 extension headers MUST be ignored (i.e., there is no attempt to translate the extension  headers) and the packet translated normally.  However, the Total Length field and the Protocol field are adjusted to "skip" these extension headers.

Notes
-----
Since the extension headers shall be removed from the packet while translating to IPv4 the translator should deduct from IPv4 Total Length the length of all the extension headers present in the original IPv6 packet except ESP header (in transport mode). AH is not supposed to be translated. RFC 2765 had explicitly stated this and RFC 6145 also should continue to have this stated. Copied the correction text from RFC 2765.
