Webb17 nov. 2024 · Identification, Flags, and Fragment Offset —Fragmentation is handled differently in IPv6. It is no longer done by intermediate routers in the networks, but by the source node that originates the packet. Removing the Fragmentation field removes costly CPU processing at intermediate routers. Webb29 jan. 2016 · An IPv6 router cannot fragment an IPv6 packet, so if the packet is too large for the next hop the router is required to generate an ICMP6 Type 2 packet, addressed to the source of the packet with a Packet Too Big (PTB) code, and also providing the MTU size of the next hop. WebbIPv6: For IPv6, which does not allow fragmentation, PMTUD works in much the same way. The key difference is that IPv6 headers do not have the Don't Fragment option and so the flag is not set.

Webb4 aug. 2024 · The full description of fragmentation in the RFC: Fragmentation. Fragmentation of an internet datagram is necessary when it originates in a local net that allows a large packet size and must traverse a local net that limits packets to a smaller size to reach its destination. An internet datagram can be marked "don't fragment." WebbFragmentation in an IPv6 network. Fragmentation is used by a source to send a packet larger than would fit in the path MTU to its destination. To send packets larger than the link minimum of 1280 bytes, a node must support determination of the minimum supported MTU along the path between the source and destination. This is accomplished by Path ...

WebbIn IPv6, fragmentation is done by only sender routers. We can also say that IPv6 uses end-to-sender fragmentation whereas the in IPv4 fragmentation can also be done by the intermediate routers if the packet is larger.
