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. :)

Subject: MTU packet fragmentation Q [7:34022]


hello, i need some help on this subject. 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?


TIA
cecil
