And if a router receives a to large IP packet is should send an ICMP "fragmentation needed and DF set" when it cannot be fragmented by the router.
The problem is we keep the payload on layer 2, so that it never will bubble up to layer 3, hence never emit fragmentation needed (we even might not have an IP address). All you see is a hanging connection.
Ah, I think I misunderstood him. My idea was that he has meshA and a meshB and between them is a normal router which connects both. In this case it would work - but yes, he probably meant one mesh and only one connection is ethernet cable (or many of them) instead of a wireless link. In this case there is nothing like a router which looks at the layer 3 stuff.
