Normally, the packet will be fragmented, sent on its way, and reassembled by the receiving host. However, there is a "Don't Fragment" (DF Bit) option with IP, and if toggled, indicates that the packet should not be fragmented by routers-- instead an ICMP "can't fragment" error is returned sent to the sender and the packet is dropped. There is are also ways to override the DF bit, but I hope this answers your question. :)

If a packet is more than the set mtu size of 1500, say packet size is 4352 bytes -does the packet get dropped? -or fragmented and re-assembled in the destination end what should be the correct behaviour? when does the packet don't get fragmented?
