IPv6 extension headers -Fragmentation• Contrary to IPv4, no fragmentation by intermediatesystems is done• E.g. If a packet is to large for a given link theintermediate node in IPv4 will fragment the packet• In IPv6 PMTUD must be done before sending apacket to a destination• An applications can however request to send apacket that is larger than the discovered• Fragmentation will then occur at the source host28
