[AusNOG] MTU Size on Ethernet carrier interconnects

[Lincoln Dale]

In a world of utopia, everyone would just enable 9216 byte jumbo frames &
be done with it.
the reality is that a variety of 'ethenet' WAN services are implemented
using a variety of silicon which predates 9K jumbo frames, and some have
silicon that only enables 1500 byte or at best a 'baby giant' frame.

i doubt anyone has <1500 byte. thats not so useable. :)


cheers,

lincoln.
