2. A large IPv4 datagram carrying a 20 byte header and 2500 bytes of payload data (total packet length is 1520 bytes) is fragmented to pass over a network where the MTU is 1500 bytes. Assume the identification of the original datagram is 123. For each fragment, show the contents of the Identification field, the Offset field, the Total Length field, and the More Fragments flag in the IP header.
