for those who interested in IPv6, Path MTU Discovery is not in IPv6 stack. To have end to end jumbo frames in native v6 we NAPs in the path should support jumbo frames.
More precisely, with IPv6 networks, either:
Sorry. I ment to say routers don't perform fragmentation of packets they're forwarding. If a packet is to be forwarded onto a link whose link MTU is less than the size of the packet, the node must discard the packet and send an ICMP Packet Too Big message to the packet's Source Address. ICMP error message also contains MTU of the link. Host can retransmit with size obtained from the ICMP message. To have jumbo frames in IPv6 from end to end and path is via NAP, NAPs should support it. Or am I still mistaken ?
