The two concepts are completely independent and orthogonal. You can have a 1280 byte link MTU on a device which happily reassembles 9x fragments into a 9000 byte payload. You can also have another device with a 9000 byte link MTU which refuses to reassemble 2x 1280 byte fragments into a single 2000 byte packet simply because it doesn't have to. Both devices are IPv6 compliant.
Well, I suppose there is 1 causal relationship between link layer MTU and IPv6 fragmentation: "how much bigger than 1280 bytes can the individual fragments be".
- simiones 2y agoOh, yes, what I meant to say is that you can send frames larger than 1500 bytes without resorting to IP fragmentation, in certain networks. I can see how it sounded like the "1500 limit" was the IPv6 reassembly limit, but I wanted to refer to the 1500 limit for a single frame.
