You're wrong here. The IXP switch platform cannot send ICMP Packet Too Big
messages. That's why everybody must agree on one MTU.
I think what was meant, no global consensus is needed, each IXP can
decide themselves what is edgeMTU and coreMTU VLAN MTU sizes in /this/
IXP. Heck, have customers vote on webpage. I guess edgeMTU obviously
will be 1500, coreMTU something else, 4470, 9000 and 9100 seem like
9180 (L3 MTU) is the obvious choice. All major core routing platforms
support it, and it's used in at least two "classic" L2 protocols (see my
earlier email).
