Hi all,
There is informative reference to MTU problem (PMTUD-Blackholes),
but nothing about MTU is mentioned in the draft itself.
I believe that MTU is among reasons for EHs packet drops,
but Fernando's statistics does not separate discard from:
- PFE restrictions
- Configured policies
- oversized MTU
Hence, we could make only qualitative statement.

Fernando,
Is it possible to extract MTU drop weight from your numerous tests?
ICMP code for oversized packet was different.
Do you keep raw answers?

Eduard

Abstract:
   This document summarizes the operational implications of IPv6
   extension headers, and attempts to analyze reasons why packets with
   IPv6 extension headers may be dropped in the public Internet.
