Hi !
Consider a packet, which gets fragmented while traversing through =
the network, such that the Fragment One has the higher layer header (say =
TCP header, with associated port numbers etc.). Lets us consider a case =
when (say) fragment Seven's TTL becomes zero & an ICMP message is sent =
back to the Message Source. At the source, there is no way of =
identifying the port number of the originator of the message.=20
In such a scenario, could you explain how would the Source handle =
the packet?
Warm Regards,
Rohit=20
