Dear NANOGers,
It irks me that today, the effective MTU of the internet is 1500
bytes, while more and more equipment can handle bigger packets.
What do you guys think about a mechanism that allows hosts and
routers on a subnet to automatically discover the MTU they can use
towards other systems on the same subnet, so that:
1. It's no longer necessary to limit the subnet MTU to that of the
least capable system
2. It's no longer necessary to manage 1500 byte+ MTUs manually
Any additional issues that such a mechanism would have to address?
