Hi Mark, Thanks for your reply. But for ipv6, fragmentation will happen at the host side.Intermediate routers will not do it and depending on the path MTU packets are fragmented at the initiator side. so while originating packets itself will do fragmentation.. Since the packets are sent with DF set as one, packets has to be dropped there itself.
If I am wrong, Please give some more explanation.
