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
