You're wrong here. The IXP switch platform cannot send ICMP Packet Too Big messages. That's why everybody must agree on one MTU.
"Someone" should do an inventory of the market to find out how many commonly used platforms limit MRU to less than 9180 (L3), if MTU is set to 1500.
Because if most platforms do not limit MRU, then the impact of MTU mismatch on the peering LAN is actually a lot less than otherwise.
However, I stand by my earlier statement that we need to include MTU/MRU in ND messages, so that this can be negotiated on a LAN where not all devices support large MTU.
