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

Status: Held for Document Update
Type: Technical

Reported by: Fernando Gont <[email-masked]>
Date Reported: 2014-08-20
Held by: Magnus Westerlund (IESG)

Section: 6

Original Text
-------------
   1.  In the IPv4-to-IPv6 direction: if the MTU value of ICMPv4 Packet
       Too Big (PTB) messages is less than 1280, change it to 1280.
       This is intended to cause the IPv6 host and IPv6 firewall to
       process the ICMP PTB message and generate subsequent packets to
       this destination with an IPv6 Fragment Header.

Corrected Text
--------------
   1.  In the IPv4-to-IPv6 direction: if the MTU value of ICMPv4 Packet
       Too Big (PTB) messages is less than 1280, change it to 1280.
       This is intended to cause the IPv6 host and IPv6 firewall to
       process the ICMP PTB message.

Notes
-----
An ICMPv6 PTB message reporting an MTU equal to 1280 does not trigger IPv6 atomic fragments. Only ICMPv6 PTB < 1280 do.

AD Comment (Magnus Westerlund): As RFC 6145 has been superseeded by  RFC 7915. In that document the above text is gone. So I consider this issue handled and not necessary to determine if it is verified or not.
