Out of curiosity, in what scenarios is it better to limit the instance's MTU to a value lower than that of the maximum path MTU of the infrastructure? In other words, if the infrastructure supports jumbo frames, why artificially limit an instance's MTU to 1500 if that instance could theoretically communicate with other instances in the same infrastructure via a higher MTU?
It is my understanding that using the max path MTU is ideal, but that not all software does path MTU discovery. Also, some badly-designed security devices can mess up PMTUD.
